The Low Fi Hi Tech headphones is a research Project to find out a way to create a fully functional pair of audio headphones without any manufactured part, this means all the parts of this headset are raw materials, such as wire, tape, solder, magnets and of course 3D printed parts.
The most challenging part was to make the right combination of 3D printed elements such as the speaker piece, the ear part had to be a good acoustic case and should to include a holder for the magnet, the speaker itself is a very thin printed part with a very thin rail to be able to insert the copper wire in it.
Once I got that part working, I decided to go further, drawing the plug to fit a standard Jack connector, this was a very tricky part because the model of this was a very thin part to print and creating the connections only with wire was a real challenge. Again it worked! And even if many people would hesitate to plug this weird looking but familiar plug, I can assure you it works with no risks on jamming inside your portable audio device.

Anyway, the sound quality is very nice against all expectations but will necessitate a power amplifier to be louder when using only portable sources like pods or phones.

The files are open to anyone who want’s to try to make a pair of these!

Special thanks to Martin De Bie, Hannah Perner Wilson, Jean Baptiste Labrune whose work inspired me a lot in this particular Project.

While designing an object for my 3D printer, I used the partial_rotate_extrude provided by CarryTheWhat. However, I realized that his routine did not work with a zero radius. I slightly modified the script to account for a new parameter to permit a partial_rotate_extrude working with a translation radius of zero.

Introducing Pocket-Dungeons! A modular, competitive dungeon-crawl for two to six players.

With modular, tile-based board design and randomized events, no two games will be alike. Dynamic, tactical game play allows for quick resolution as players control treasure-hungry dungeon delvers vying for gold and glory.

This game has been designed with Pocket-Tactics in mind and the pieces and rules sets will be able to cross over and expand the depth of each range.

For the Pocket-Tactics stuff, head on over here: thingiverse.com/dutchmogul/collections/pocket-tactics-sets

Also, check out our blog for updates on our projects, contests and the like: illgottengames.blogspot.com/

All models were designed in Sculptris and Tinkercad

Print your design with a new 3 mm wood-filament.

Well, I started out wanting to do some nicer fillets on my OpenScad designs, and suddenly, I have a full blown Bezier surface/solids library!

This thing is the Version 1.0 for this stuff. I think it's actually good enough to produce some nice looking objects.

The technique used here is a linear extrusion of a bezier surface. The surface itself is described by 16 control points in a mesh. The machinery then takes care of rendering that to the thickness that you want.

The workhorse module can be found in the Renderer.scad file: DisplaySurfaceMesh()

This will generate a surface, according to your mesh, and extruded to the thickness that you specify (default 1mm). It is a solid, so it will play nicely with the other CSG functions in OpenScad.

There are a few demo/test/samples provided in the .scad files, so it should be fairly easy to make up your own examples.

I use colors in the examples because it makes for some pretty pictures. They don't affect the rendering process at all. If you don't like the color ramps, you can select your own.

Although this version provides only one mechanism for doing solids from the Bezier surface mesh, it has all the fundamentals for you to do other forms as well. you don't even have to use the Bezier functions for bezier surfaces, you can use them for anything where you'd like something to vary in a parametric sort of way in your designs. The color ramps are another example of how the Bezier curves can be used.

At any rate, there are other forms of curves, and more rendering methods to be pursued. RapCAD is doing some interesting work, and hopefully Bezier shows up as a core feature of these various text based tools.

But, until that day... enjoy!

Build your own colorimeter! More details can (will eventually) be found at appropedia.org/Open-source_colorimeter. Note that present firmware only reports absorbance and transmittance; a calibration protocol is forthcoming.

More and better to come...

The STLs will build a case for a colorimeter and the electronics BOM will yield a device designed for performing high range Chemical Oxygen Demand (COD) determination, measuring absorbance at 606 nm, an absorbance peak for the chromic ion. The cuvette holder is designed for Hach COD digestion vials.

The light source was specifically chosen for chromic ion determination; it can be altered to measure other ions (aquarist: think nitrates, ammonia and pH). We're working on other designs and useful applications and invite you to join us and share your designs.

Colorimeters are exceptionally handy items used for determining the concentration of dissolved species typically in aqueous solutions. The principles of operation are simple and form the backbone of several other analytic methods.

Here is a simple illustration of the Pythogorean tiling of a sphere. The idea comes from a web page by Willian E. Wenger which explains how to carve a periodic tiling on the surface of a sphere.

miracerros.com/artwork/g_sphere_layout.htm

A cube was used for this example. A simple two dimensional pattern with 4 fold rotation axes was generated. Nine copies of the pattern, which extends to infinity, are shown in the image above. Each cell has a 4 fold rotation axis at the center and a 4 fold rotation axis at each corner. One interesting thing is that the 4 fold axes at the corners are converted to 3 fold axes as the pattern goes from 2 to 3 dimensions.


To tile the sphere six copies are transferred to a cube - see images. The conversion to three dimensions changes the 4 fold axes at the corners to 3 fold axes on the cube. The 3 fold axes are preserved when the cube is converted to a sphere.


Three dimensional objects are the cube with the pattern transferred to its faces:

cube_with_pattern.stl

and two versions of the cube converted to a sphere:

sphere_with_pattern_50.stl
sphere_with_pattern_70.stl

Look at the corners of the cube. Now consider what would happen if the cube were flexible and inflated to a sphere. On the sphere the centers of the cube faces are represented by 6 hypocycloids and the corners by 8 distorted triangles.


OpenSCAD creates the correct symmetry for the "tiling" of all the Pythogorean solids. See things 40276, 39977, 39818, and especially 39424 which has a similar example.

So here is a CAD drawing I did in OpenSCAD of a concept for a ring with a screw-on top.
the top has a hole in it for an LED.
There is a side hole in the ring for a mini-usb connector. That needs to be shaped a little more but good enough for now.
Note the top has a cavity to increase the payload space.
To think about the size of this, the ring will screw onto a 2-litre pop bottle like a bottle top.
so vertically large, but we can overcome that later when we physically prototype.

A handy case with a detachable probe to house your Geiger Counter kits. I designed it to fit the DIYGeigerCounter v.4.1 board (https://sites.google.com/site/diygeigercounter/). I've included a version without standoffs for those of you who wish to fit a different kit.

[Revision] The Handle grooves have been removed. Otherwise, it would of been impossible to print.

[Revision] Probe holder design changed. The probe now slides into the holder vertically. This change minimizes the effects on the holder from warping.

Hey Watch it.

The Design Team over here at MakerBot have perfected the art of making links for this MakerBot Watch that print in place without needing to be assembled. Once removed from the build plate, they move freely, and can be taken apart and snapped back together. Feel free to download the design and adapt it for your own purpose.

Other awesomeness:

• Mix and match your favorite colors to create an awesome watch for any occasion! Contrast the band with the pop-out bezel, or make links in multiple colors for an interesting two-tone band.
• An assembled version of the MakerBot Watch is available for sale at the MakerBot retail store!

Stick it to the man (figuratively only please!) with this open source, fun and completely functional butterfly-comb!

All the flash and guile of a butterfly knife, but your fingers get to stay attached to your hands!

Based off of Techno264's excellent design, this blade has wider, curved teeth which print easily and won't break off. Also, the comb now has a blood groove, and an angled tanto point for an aggressive look :)

The butterfly-comb is completely harmless, fun to play with, and a you can really comb your hair with it!

It prints in minutes, so you can use it to impress friends when giving a demo of your 3D printer :)

I will be posting a video about the comb on my site shortly: fabberforge.com

Update 12/2/2012 1700: Added experimental untested comb with pointy teeth :)

Update 12/2/2012 1800: Added a second experimental pointy tooth comb :)

Update 12/5/2012 1828: V2 Comb Blade uploaded. It is 1mm thicker (more sturdy) and has pointed curved teeth.

All parts for making a cigar box ukulele except the Cigar box.

This project started as a thought piece around printed consumer electronics and the idea that they could be as easy to turn into working product as they are to print. Meaning that once off the print bed, such an object could be assembled without any tools, and be made functional by readily attainable components. Being electronically simple yet functionally complex, headphones seemed like a good fit to stress test this premiss. The first go at this idea resulted in good looking, well working model that we created at our studio on a professional ABS FDM machine (Dimension 1200ES, print time about 13 hours and 30 minutes, hence the name). It worked well here, but the machine we used is not very accessible to the average maker, and two of the critical parts relied heavily on soluble support printing that this machine specializes in. To really test this idea of printed CE, it needs to be created by the people who would use it. To this end, I have begun to adapt the design to the Maker Bot Replicator. The main challenge being how to build to a similar level of quality and without soluble support. With a bit of experimentation, I am pretty confident it can be done. So look for some updates on that soon! In the meantime, here is the current model(s), component list, and instructions to make your own working headphones right now.

File update(10/15/2012):
Did some further work on the 'Replicator' version of 1330 last week and this past weekend. As mentioned above, the goal of this mod is to create self supporting speaker housings that builds cleanly on single material printer with out the need for soluble support. So far its been a real interesting discovery process and this latest version, called V2, is actually the 5th iteration of this challenge. V2 still requires some custom breakaway support structures (in the file) so its not quite there yet, but it is real close. I have uploaded the latest STLs for V2 1330 headphones for you to try out. Enjoy!

13:30 CAD files on Teague Labs (10/15/2012):
For those of you who want to do more than just print the 13:30 headphones, you can now download the Iges and STEP versions of the CAD files at labs.teague.com/?p=1509. Download, customize, and print you own version! We would love to see what you come up with!

A printable clutch (purse, evening bag, etc) for desktop 3D printers. I've been a big fan of Zomboe's things, and have been eyeing his chainmail designs since I bought my TOM last year. There are lots of 3D printed fabric applications for pro-grade printers on shape ways, etc, but not for use on reprap or makerbot style printers. Building some awesome and wearable feminine accessories has been on my to do list for awhile.

Goals:
1. Functional purse that will hold an iphone.
2. Print and assemble without glue
3. Attractive and durable enough to actually use.

I did not succeed on these counts. This project is less a work in progress, than an abandoned proof of concept. But, it's time to get it off my hard drive and out on the web. I expect to try again, with some lessons learned.

The problems:
1. This took 24 hours to slice in RepG. That's longer than I want to wait, and too long to iterate quickly. I either need to simplify the geometry somewhat, or use a newer and faster slicer.
2. It's difficult to get every corner to stick to the platform, especially with a second extruder interfering and prying up a loose ends. Aggressive solutions like applying ABS slurry to the platform result in a less than desirable surface finish, and a lot of kapton tape to peel off the print. One missing square, and the print is ruined. There are about 5 holes in my print.
3. I haven't solved how the sides go together. Currently, I think a blanket stitch with plastic lacing used in kids' friendship braclets or embroidery floss should suffice. But it's not a great solution.
4. To be functional, this design really needs a chain or wristlet loop.
5. I could make a nicer looking design if I altered my approach from no-glue-snap-together, to allowing multiple pieces.
6. The hinge works well, but needs to be a little beefier to hold up.

I was happy with how pretty and shiny the fabric looks. With a more attractive shape and clasp, I'd wear it. There are cool options for textile prints with dual extrusion if I could just get everything to stick better.

The "fabric" only bends in one axis on each side, which you should take into account if use it in another way.

Keychain loop's position changed to be on top of the heart so that you could use it as a pendant on a necklace or as a car's rear view mirror ornament!

Update 10/17/12: I printed this out at 20% fill like everyone else but it broke. So, to increase durability, I printed it out at 50% fill. However, at 50% fill, the plastic heart is hard enough so that it won't deform anymore to accomodate the large diameter pins. Therefore, I redesigned the pins to be smaller in diameter so that it could be easily assembled.

Update Nov 1, 2012; New skinnier pins designed and the heart gears's stl file was recompiled from source and reposted, "keypins6, platenokey4b."

Update Nov 24, 2012; updated to new pins and key. I found out why some people get perfect fit while others mysteriously have pins that don't fit or was getting perfect fit and then suddenly gets pins that don't fit. Small features such as these pins are much wider than as seen on CAD software because the plastic's first layer is squished against the HBP, causing the first layers to be wider than they are supposed to be. Furthermore, the holes on the gear pieces are smaller than they're supposed to be for the same reason. Also, the holes on the central hub are not printed on the HBP so they are more size accurate. Therefore, there is very little print size variability tolerance so if your machine is slightly calibrated differently, the filament is slightly different in diameter due to different humidity levels, etc, then the affect on the pin size, though small, may cause it not to fit anymore. In other words, the pins are almost too big for the gears while almost too small for the central hub. I improved the pin design by making one end wider for the central hub while the other end is narrower for the gear pieces. I also shaved a little bit of width off the pin heads and the central key. I also included slightly smaller and slightly bigger versions of the pins and key, just in case. Perfectly sized and shaped pins and key file is keypins12.stl. Bigger perfectly shaped pins and key is keypinsbg.stl while its little sister is keypinssm.stl . Problem solved. Enjoy!

Is your roll of super-wide Kapton tape lounging around, taking up space? Put it to work!

This is the first design of my KaptonCaddy! Just place your roll of tape on the base, and slide in the caddy core. It snaps together and becomes a handy carrying-case for your allen wrenches, nuts, bolts and other sundries. It has two swivel drawers, holes for tools and a basin up-top for bigger stuff.

UPDATE V1.1!

The base is now part of the body. The tape roll now acts as a sleeve to hide the drawers. If you store any over-sized things in the top (like calipers) you may need to remove them to lift the roll off.

Test print #2 on its way!

Enjoy!

A sequel for the printable padlock: a locking box with a real locking mechanism and a sliding lid.

Uses the exact same locking mechanism as the padlock and is fully parametric.

3D model of the water bear or tardigrade (Echiniscus species) - possibly the most widely spread and amazingly adaptive multicellular animal on Earth. They are cryptobiotic and have been demonstrated to be able to survive exposure to outer space for extended periods. The animals are about 0.5 to 1.0 mm long, so this is a 60X blow-up.

This is a very hacked attempt at a SF 50 profile that will let you print your object on the right (T0) Replicator extruder while printing support using the left (T1).

**Update** I am now building these and selling these on my Etsy! So if you don't have a printer yet, I will be happy to print you one! Check it out at etsy.com/listing/109657227/

Update 2: I've been making a lot of little changes that I realize I never uploaded here. So now I have. V3.1 for your consuming pleasure. All pieces are now the latest version. If you want the old version, I don't know why, you can still get the plate.

Featuring improved couplers for easier assembly and disassembly, better proportions and appearance, and a more printable design.

Carry your chess set to your next game in the coolest way possible.

Was looking for some lower cost plastic for my Replicator MakerBot. Turns Octave sells a bunch of colors on Amazon for reasonable prices. Unfortunately, after purchasing, I realized that the spool is of a different design than what you get from MakerBot. The spool is not only thicker, but has a much smaller hole. So what better solution than to make my own holder. So I cranked out a quick design based on the original MakerBot holder design, but one that fit the hole of the Octave spool.

One of my favorite things about using a MakerBot is that you can watch things get created right in front of you. This allows for awesome opportunities to add to the process while it's being made. With this ring, I carefully (extruders and bed are hot!) place beads and gems inside of the ring which get encapsulated. The beads rattle around and make for some noisy maraca style rings, and the gems look great through transparent PLA!

Can you stack these gyroid modules into a pyramid? It can be a little tricky to get them to all line up properly, but you'll know you have it because the larger gyroid you create is highly symmetric, as evidenced by the gridwork of holes that run through it in many different directions.

Each module is a rhombic dodecahedron intersected with the gyroid, and hence this puzzle involves forming a face-centered cubic packing. Due to the way the module is oriented, it prints beautifully without support (better than the cubic original).

You can make this puzzle as large as you like; the more you print, the more you can stack.
