This is an attempt to combine various aspects of Adrian's and Wade's extruder drivers. Specifically, It keeps Adrian's extruder clamping system, uses a prime number of teeth for good wear characteristics but uses Wade's hobbed bolt to do the driving.

As the name suggests, the design uses Herringbone gears. This ensures that backlash is substantially reduced, which should result in the extruder requiring slightly less reverse, but more importantly run quieter. The design of the drive gear is somewhat experimental. As with other gears, this uses a grub screw to secure the gear to the motor shaft. However, on this design the hole goes through the root of one of the teeth. This takes up less space, and also lets you adjust the position of the gear without taking the motor off. However, it is quite intricate. Many people have managed it, but your printer needs to be running well to do it.

This is a tribute for our teacher Obijuan ( thingiverse.com/obijuan ) that is among the ones that introduced me to the world of 3d printing.

It is a custom Wade extruder gear that has some Rebel Alliance symbol as holes on it.

My wife started needle felting, so I printed a handle to hold the little metal needle that is used. This is a WIP because I still need to design a cap.

There is a cavity in the middle to capture the hook. This was designed for a 1.8mm diameter needle with a 5mm bend on the end.

This is inspired by the Slim from Human Republic.

I found an article on Gizmodo and saw this slick money clip. (http://ideacious.com/details2000000051.htm?S=4216720422&L=0)

I sketched this model up and now you can print it out and see if you like it. If you do, please consider buying it from the original designers.

1:100 scale model of the International Space Station. 3D models were created using AutoDesk Inventor using sizes in Inches and exported to .stl files. Models came from the NASA website at
nasa.gov/mission_pages/station/multimedia/scalemodel/index.html

I have created these files in anticipation of making them with my recently ordered MakerBot Replicator. This will be my first attempt at 3D printing and would appreciate if anyone does attempt them, to post some feedback. I will update once my bot arrives and I have a chance to test it out.

This is all the skp files that Brook Drumm uploaded. I have simply put them all in one file and arranged them how I think they go. Can't be exactly right till I get mine. I'm a backer of his Kickstarter project.

Thanks Brook!

One part is still not a skp file. It's easy to pick out. It's an stl and it's the front part in the image. Lots of lines show up.

This is a half-size version of Stefan's double-size minifig, with added attachment posts – you may have to shave the posts to get them to fit.

This is the real deal, no derivatives here. These are the real Printrbot in it's current version. I have a bunch of these printing all day, every day.... it works. It is expandable to larger widths and heights easier than any other reprap out there. Period. Its the most inexpensive bot out there being mass produced. And, its now yours to print, build, improve, change.... whatever you like. I can't wait to see what you do with it. I will post pics of all the various forms it takes, news, etc at printrbot.com

The cartridges used in an old Dimension make great spools, except you don't see how much filament is inside.

After having put a PLA inside sign on it (http://www.thingiverse.com/derivative:21217), I thought to replace the useless chip instead :)

The text is a little too small, still readable but I'll improve it.
Otherwise, I may try to adapt or make something to just hold the spool alone (49-52mm dia. for the center).

Set of planetary gears and arms to hold the planet gears in place.

Based off OpenSCAD code from thing:7390 (after cutting out significant portions of it - because the original thing is much more than a toy).

The gear ratios are very interesting, and (at least at first) non-intuitive, depending on the part that is held stationary.

With a fixed Annulus or Sun, this gives 1:6.
With a fixed Planet carrier, this gives 1:5.

Storage cabinets are great for organizing small parts. Unfortunately the one I recently bought from Lowes didn't come with drawer dividers, so I fired up OpenSCAD and made my own.

The script is fully parameterized so you can customize it to fit whatever drawers are out there. The default values fit the smaller drawers on a Shop Stack-On 39-Drawer Storage Cabinet ( lowes.com/pd_124553-941-DSB-39_ )

For updates, check out the code on github: github.com/jherrm/Drawer-Divider

Pretty simple kids toy. Attach a balloon and watch it scoot across the floor! (Sorry, some extra parts required)

This is a simple handle.

Hopefully a Salt Shaker soon...

The youtube video here youtube.com/watch?v=DBnKPEnt9a4 shows how to add flats to motor shafts that do not yet have them.

Loosely based on the "Vise pad for holding 8mm threaded rod by ChatterComa" I created the part that helps you to grip the motor shaft properly in place so that you do not apply force to the motor inners.

A simple holder of 6 toothbrushes. Fits most standard toothbrushes and keeps them off the countertop

parametric cube puzzle

A bit frustrated by not being able to print the threads on this nice hand drill: thingiverse.com/thing:6285
I decided to experiment with my own threads so I can make a derivative.

This is a 90° thread in stead of the normal 55-60°.

It printed nicely on my Cupcake and the 2 parts fit quite nice together.

Update: please follow this link: thingiverse.com/thing:16682

Build a name plate with any text!

OpenSCAD script allowing you to define the text and the script will generate a nametag.

After watching the great triffid_hunter design I adapted mine in order to fit a Sells Mendel.

This is a nice addition that simplifies the printer, saves vitamins and contributed to a better world.

This thing will create a range of metric and imperial tooth profile pulleys, with any number of teeth, specified in the Openscad file.
Tooth profiles currently supported are MXL, 40DP, XL, H, T2.5, T5, T10, AT5, HTD (3mm, 5mm, 8mm) and GT2 (2mm, 3mm 5mm).
There are a range of editable parameters for editing the fit of the tooth (to account for printer variation), the pulley base, captive nut(s) slot for the set screw, motor shaft diameter, pulley height and belt retainers.
The attached stls are reference pulleys, mostly around the size used on repraps.

Details
After creating the parametric pulley thingiverse.com/thing:11256 I realised this way of modelling them was only going to work for square-toothed pulleys, and a way of producing pulleys for belts with better characteristics for linear motion was required. I found dxf drawings of the relevant tooth profiles here oem.cadregister.com/asp/PPOW_Entry.asp?company=915217&elementID=07807803/METRIC/URETH/WV0025/F and modelled pulley diameter from data here sdp-si.com/D265/HTML/D265T016.html
There were a couple of possible approaches to importing the data, I chose to simplify the bezier curve dxf data in Inkscape, producing vertices with a resolution of around 0.05-0.1mm for each tooth. Another advantage is the the pulleys have the tooth ramp for smooth entry and exit of the belt tooth into the pulley. I'm not really sure 3D printers can take full advantage of this yet, but quality is improving all the time!
If other tooth profiles are required, or you model any, please pass them on to me and I will include them.
Not printed yet... I'm away for the weekend! I'll upload some photos when I do, on Monday.

I made these simple little hooks to fix a broken washing hanger, but they turned out to be pretty useful for other stuff too. They can be linked together to make a chain. Maybe useful for filament or cable guide. If you attach one end to a rubber band and tie it to your bot somewhere then clip the filament into the other end of the hook, the hook can be used to gently guide your filament.

This is a slightly more challenging variant of Dovetail Triangle that only opens when held in a certain orientation.

Watch the video for a demonstration:

youtube.com/watch?v=JnMRREjfPyc

I got a little carried away making a winder for my new earphones.

I designed this broder based on mraisers design for sublimes 3d printed game tiles. Like mraisers mine interlocks using dovetails, My border however is thinner and has a nicely beveled edge. Future design changes will include integrated card holders.

- Got a Mom?

- Does your Mom have a desk?


If you answered "Yes" to the above questions you may want to print this.

This is another Faja/Daja project. My 3yr old daughter saw a picture of Mom's new cubicle system at work and said "it looks real sad" so we talked about making something special to sit on her desk that she could also use. 30min in Sketchup, 4.5hrs print time and we are ready to deliver some ABS joy to Mom's desk! I told my daughter that I would be able to give this to my Mom (Grandma) as well and she doubled in excitement making sure I would tell Grandma that she helped make it too!

** bmsweb alerted me that his Mom is a Mum, and Mum's count too! **


Love Ya Mom!

This is a smaller version of the filament drive made by Jag. I made this from scratch in Sketchup, but based most of it around his design, because the larger 3mm version worked well. This, and the 1.75 settings were all I needed to immediately get the thinner plastic working. Requires no extra support, they are built into the model.

For all cthulhu followers ;)

this is a mount designed for Prusa based machines. It allows for top mounting of filament spools. This particular model works with Ultimachine and 3D printerstuff spools up to 5lb.
