All the RP parts for Mini Mendel in 1 sheet, with a 80x80x.005mm sheet for comparison (dang that's not much stuff to print).

Rhys Jones was nice enough to clear up some of my issues with the parts list. These parts are for the FULL Micro Mendel, with the filament & electronics underneath.

Not supported, not recommended, but now available in an easily printed form.

Dremel Flex-Shaft + MakerBot + MakerBeam + OpenSCAD = (Micro CNC Mill | Drill Press)

Expect future refinements, but this is the first version that works on my Batch 1 MakerBot.

Lets be clear this is a laser man bracelet. Not a bracelet. However women can wear this if they choose. It still is a laser man bracelet.

I was trying for masonite chain link\\\\\\\'s however I am stuck on making a matching sprocket. You can see from the photo that it goes.

2 Holes, 3 Holes, 2 Holes.... This is a funky hard to make sprocket.

For now its a laser man bracelet.

UPDATED 2010-01-28 : Added extruder carriage, cleaned the code a little.

In the spirit of Open Source Hardware, Dremelfuge is now Open Source Hardware, according to the 0.3 standard found here: freedomdefined.org/OSHW

DremelFuge is a printable rotor for centrifuging standard microcentrifuge tubes and miniprep columns. Compared to the cost of a new centrifuge (priced by a fellow Thingiversian at $500 minimum on Froogle), a Dremelfuge is incredibly cheap. It can be used for DIYbio ( diybio.org ) or for some culinary uses. It requires industry standard 1.5ml/2ml Eppendorf/Microcentrifuge tubes.

* Used with a drill at 3000 RPM, the Dremelfuge will deliver over 400g, enough to comfortably spin down Miniprep samples (proven personally). It will likely achieve acceptable results at lower speeds, too.
* Used at 10krpm, on a Rotary tool for instance, a Dremelfuge should deliver over 4400g, more than enough to spin down bacterial cells.
* At 16krpm, Dremelfuge matches commercial centrifuges.
* On a Dremel 300, a maximum speed of 33krpm equates to a force of over 50,000 times earth's gravity, which puts it into so-called "Ultracentrifuge" territory. The latest version (as printed by Shapeways) has successfully spun tubes at this speed.

Dremelfuge is available for sale as a high-quality, robust print on Shapeways.com in two editions, each suited for up to six samples at a time: Dremelfuge Recessed Edition, to fit the cutting-tool-holder commonly found with rotary tools (5mm diameter bore), and Dremelfuge Chuck Edition, which can be quickly adapted for use in any machine with a chuck grip. They are both available here on my Shapeways shop:
shapeways.com/shops/labsfromfabs

Dremelfuge, as with any high-speed rotary tool, may cause personal harm or damage to property or persons in case of failure, and no guarantee, warranty, promise or suggestion of safety is made or offered by me (Cathal Garvey) with regard to DremelFuge.

RotaVac is an experimental "centrifugal compressor", designed to be printable as a single piece and spun in a drill or machine to generate a negative pressure gradient.

RotaVac is designed to fit a standard 608 bearing like the sort used in Makerbots, so that a small nozzle (printed separately?) can be fitted through the bearing interior.

This is a pure experiment, and I'll post more when I have a chance to test it!

I wrote a script to generate lasercut boxes. The script reads a config file with the box dimensions and generates a DXF file and an OpenSCAD model. We use the script for all types of cases here at metalab. The example file attached is the case of our electronic door lock system.

The script can be found here:
svn.clifford.at/handicraft/2009/boxgen/

You might need to install SPL (the scripting language I've used for the script) before you can use the script:
clifford.at/spl/

Notice: This is a project in development, and I intend to improve it over time. This draft will work, but it's hardly ideal. Caveat Emptor!

Update Jan 31st: I've uploaded Version 2, which is pretty much the same as 1.5 (which I've removed as a result) but comes with the "Hex Key Holder", which can be fitted with a standard screwdriver bit from a powertool to act as a crude "center". My experiments with using two such centers to drive the lathe weren't great, as one invariably ends up spinning and the piece stops. So it looks like the required parts at present are: Two Bearing-End-Body Sections, two Bearing-And-Tool-Fittings, A Boltplate and a Hex tool holder. You'll also want a Dremel Rest and a length of MDF/wood to bolt it all down to. And you'll need googles, and perhaps gloves, and a lot of sense.
For now, it is left to the user to figure out spacing of the body sections and how to align them. I'm working on improving that. :)

More Update: Really bad video of me demoing Microlathe: youtube.com/watch?v=6XXN6UkrnIw and a shot of the finished piece of dowel on my Twitpic: twitpic.com/y8jnl
Also, Microlathe was featured on Makezine! blog.makezine.com/archive/2010/01/tiny_printable_dremel-powered_lathe.html

Microlathe is a little dremel-powered woodturning/watchmaker's lathe that can be printed and bolted together with all those leftover M3 nuts and bolts that came with your Makerbot. In addition to the M3 nuts/bolts, you only require a 608 bearing (I got an extra one with my Makerbot) and an 8mm diameter spring to fit the bearing-end. You probably don't even need that spring.

So, if you have a Dremel handy, you can consider this "The Lathe That Came Free With The Makerbot"!

Microlathe is Parametric, and makes use of a "Global Parameters" script from which the others derive shared traits such as the radius of the bolt plates, etc.. you could try printing a larger one, but bear in mind the limited space you have to print the body portions, which are already quite large for a Makerbot.

MicroLathe makes use of shapes.scad, which was kindly released to the community under the GNU General Public License by Catarina Mota. Permission was explicitly granted for shapes.scad to be considered released under an Attribution, Sharealike license additionally in this case, to facilitate licensing crossover. Thanks a million Catarina!
Microlathe also makes use of teardrop.scad, which was provided kindly by Erik De Bruijn. Teardrop.scad is released under the GPL2 license, with the inheritance clause generously waivered in this case to permit release under a non-GNU license. I'm very grateful Erik, thanks!

I'd appreciate a small donation via Paypal if you find yourself using this to generate a profit (selling turned items, etc.), or if you just love it and want to show your appreciation. Otherwise, it's all yours to print for yourself or others! Just don't charge for it without asking me and informing the buyer that it's available freely here.

This is the next step in my attempt to make a Sarrus linkage based 3D printer. The idea is to have a cartesian mechanism without those long rods and bearings.

I built three of the Mark III and mounted them in a x-y arrangement as shown. They can move over a square about 105 mm wide, and someday may carry an extruder. They are driven by DC motors taken from inkjet printers. These motors are driven in a servo arrangement using quadrature optical encoders and optical strips removed from the same printers.

Okay, this is not quite done, but I thought I'd throw it out there anyway.

This version is less prone to cracking. Instead of a washer and nut, there is an M6 tapped hole in a piece of aluminum. But best of all, two can be bolted together to form a dual head extruder. Yes, you can have one or two of the same extruder! I'm working on a mount for this right now.

See my YouTube videos of previous versions for theory of operation (http://www.youtube.com/watch?v=HMjVrmLJvIU) and how quickly the filament can be changed (http://www.youtube.com/watch?v=z_isuzpvjBc)

Even though there are lots of great gears on thingiverse, I couldn't resist the urge to model some too :)

The combinations of parameters are too many to upload an STL for each, so I just picked a few.

I also made a version for helical gears: thingiverse.com/thing:1339

Snowflake Tree Ornament for your Xmass tree and/or gifts.

Initially I haven't printed this out due to storm tossing the boat around that night. But hearing that we're likely to have a supply of PLA soon in the US I felt inspired.

This shape is a world record holder you need 20 tiles before it will tile the plane periodically (10 up to symmetry). It fits together in an amazing variety of ways but can easily block itself. Making it a fun puzzle.

The tiles were found by a massive computer search by Joseph Myers. Look for this and other puzzling shapes at: srcf.ucam.org/~jsm28/tiling/

The idea to make physical tiles was originally from Chaim Goodman-Strauss: mathbun.com

I thought it would be point less to publishing this, but after seeing "Sumobot Chassis by langfordw" I said to my self why not. The EEEI Robotic ieee.rutgers.edu/robotics/ club at Rutger was inviting all student to joint the line following competition to build a robot from a kit. More detail description of the kit can be found here ieee.rutgers.edu/robotics/attachments/069_Kit_Description.pdf. They also made four classed meeting once a week for student who have no skill in soldering or programing to assemble the kit. After the four classes student have two week to prefect their bot before the competition. The kit costs $65, but since I already had Atmega sitting alone in a box I decided to get the kit without the Freeduino for $45. I got chance to use the Atmega and learn how to program it. I could not let this opportunity just pass by.

This is an STL file 3D printer ready.

This is a knob to put on top of your z-axis screws. The holes are made to be tapped with an M8 tap. Harbor Frieghts tap kit is $12.

Here is a squeeze buckle like you normally have on a backpack or hiking gear. I removed all of the supports for a strap on the fork part, since it just wasn't printing properly.

Also the fork fits into the sleeve in only one direction, due to the edits I had to make to make it printable.

Enjoy!

There are some little plastic mounts used for attaching mini servos together. They are NOT strong enough to support any weight, but they work well enough for playing with the servos. I used this assembly to test some servo control ideas, including inverse kinematics for positioning. More information available here: blog.notzero.net/2009/11/playing-with-servo-motors.html

The models were made in SketchUp. The parts in the SketchUp file are all scaled by a factor of 1000 (meters instead of mm), because SketchUp gets weird with small dimensions.

I've included a rough model of the servo motor used, which can be used to design other parts that attach to the motor. The mini servos I used are less than $4 each from DealExtreme: dealextreme.com/details.dx/sku.20023

This is a prototype magnetic linear encoder board. I messed up the footprint, so the board is not functional. I'll fix this and get a v1.1 out ASAP. Gory details here: blog.makerbot.com/2009/11/10/monday-rd-fail/

The board itself is going to be very awesome: Sporting the Austria Microsystems AS5306 chip which is a magnetic linear encoder. You put down a strip of adhesive backed magnet and then run this chip over it. It will tell you your exact position over the strip down to 15 microns. Hawt.

These are MakeBeam 10cm prototype .STL files that have been run through "Magics 14 64bit" to remove all kinds of errors and make play nice with the majority of 3D printers throughout the world... (courtesy of Materialise)
I've included a 254mm (10") for yucks (if you print on a Dimension - wrap it with support material otherwise it will bend on you ...)

Note: as a curiosity I made a horizontal an a vertical lay/orientation - and as you would guess the horizontal is a lot stronger. If I had unlimited funds, it would be interesting to do real testing to see at which orientation (90, 60, 45, 15, 0 with rotation components also - permutations get astronomical), would be best to build for overall beam performance verses maximizing in a single plane of force (vertical lay/orientation with no side forces would win hands down, compression load only)

I found the warning sign in a blog post about future warning signs lifeboat.com/ex/warning.signs.for.tomorrow and immediately knew that I needed such a sign for my Makerbot.

Because the original pictures are very low-res the auto vectorizing did not work out too well so I redrew it as a dxf using a stencil font.

A nice little wine glass for drinking your port wine in. The first version has a bit of problems with overhangs, and the second version fixes this, as well as adds a few flourishes of its own.

This model was made with OpenSCAD, which is an awesome CSG based modeler. More info here: openscad.org

The Frostruder MK2 is a radically different approach to frosting extrusion. Instead of using a motorized plunger approach such as with the Frostruder MK1 and Fab@Home paste extruders, we've switched to air power. The result is a Frostruder with excellent characteristics: nearly instantaneous start/stop capability, vastly simplified design, a high pressure capacity, and an awesome steampunk aesthetic.

The way it works is pretty simple: The frostruder is basically a syringe connected to a pressure source, typically an air compressor. There are two solenoid valves to control the pressure: a 'Pressure' and a 'Relief' valve. When the Pressure valve is on, the syringe is connected to the main pressure source and that pressure forces out whatever paste material is in the syringe. When you wish to stop the extrusion, the Pressure valve is closed, and the Relief valve is opened. This part is critical because even after the Pressure valve is closed, the syringe is still pressurized. By opening the relief valve, the pressure is released and the Frostruder stops extruding almost immediately.

The frostruder is capable of extruding nearly anything with a paste-like consistency. There are many materials to possible, from food based items to awesome engineering resins. So far, we've had success extruding the following materials:

* Frosting
* Peanut butter (creamy)
* Jelly / Jam
* Nutella
* Clay
* Silicone
* Epoxy

Designed for an upcoming robotics competition at WPI in which the robots must "improve quality of life" in some way:

Bloombot is an open-source automated hydroponics system that aims to build community and increase the engagement of people with their food. Bloombot is capable of growing plants like lettuces and herbs throughout the year and, through use of Twitter integration hopes to build off the work of other products (like AeroGrow and Botanicalls) to integrate some of their functionality to produce a machine that is greater than the sum of its parts.

Still working on finishing up the parts list but it's almost complete.

Largest figure that can rotate all the way around within a square.
Make a box and a rotor. Fit Rotor inside the box. It (should) rotate freely.

SSS (servo suspension system) is designed to support standard servo motors and act as a basic suspension. It is still a work in progress and has not been tested yet.

Will update results soon.

My thing has no expecific function, it´s just a composition of two objects that interect with each other.

Power outage? Trying to save the environment? Dont need to illuminate the whole room? Whatever your reason, all you have to do is print, bend, and CLIP.
