Since the thingiverse needs good robots to fight the bad ones, i give you R2! I've modeled the full scale version in inventor and put the files here. I've also made an attempt to make it printable. However, since my printer is currently down for repairs, i'm hoping someone else will give it a shot and let me know how it goes!

Obviously design credit goes to lucas film, but the 2d design files came from the r2 builders group, and the 3d is the result of days and weeks of modeling and guessing. May the force be with you :)

I like the polargraph controller
polargraph.co.uk

but its current choice of electronics somewhat limits the choice and size of stepper motors one can use.

I went with stepstick drivers with 1/16 microstepping and modded the polargraph firmware to work with step/direction drivers.

Note: my printed files are here: thingiverse.com/thing:16692

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

This is an apparatus designed to allow three people to conveniently type out a specific phrase: it is as it is

Each person must time their actions specifically, and operate their portion of the device with care.

This device was made to be a performance at a local art-event. Its operation is (of course) far from convenient, but it does type out the most true thing I have ever known.

Original project idea was inspired by TheMechatronicsGuy.

Mr Clicky is your desktop friend. Design and make him custom arms, legs and hats. :)

He stands aprox 240mm high when assembled (he's BIG). If you want to print him you might need to play around with the file a little; he's very intricate (thin walls, hollow) and was designed for and made using SLS at shapeways. If you scale him down and do a print please show me! I'd love to see.

If you must have your own Mr Clicky but can't print him, I'll be putting him on shapeways shortly. :)

While playing with my Moon Rover tread, I found it zipped into itself pretty well. This is an adjusted version that can zip into both sides. It's flexible in several dimensions and easily layered. It's quite fun, and I'm curious what uses or interesting shapes you all can come up with for it.

This is a teminal block that I designed more for a test than anything. Buried inside the object are five hex cavities for holding nuts (see the cut-away photo). During the print, the ToM is paused and five nuts are dropped into place. When the print continues the nuts are covered over except for the screw hole. The design places a single layer completely over the nut to assist the structure above, but it is easily punched through when the screws are installed. This produces a much stronger screw thread than tapping the plastic.

A few months ago, my school was getting ready for a theater run of "The Little Shop of Horrors" and needed a tripod that could mount a video camera and be controlled from back stage wirelessly via radio. The whole idea behind the thing was that at the end of the play, when the plant achieved sentience, a camera, hidden inside of the huge plant, would look around at the audience and pick-out one member of the audience to devour.

I was most dismayed to find out that junior year of high school is not the most forgiving time to be trying to bang-out a completed, complicated, reliable device involving software, electronic and mechanical hardware as a one-man development team. A student needs more than 4 hours of sleep every night to be able to at least attempt to hold an intelligent conversation once a day for the duration of the school week.

I did not manage to finish the actual mechanical part of the assembly in time for the run (it's missing the all-important camera mount) but managed to finish all of the gears, mounts, wiring, soldering, OpenScad and Arduino/XBee coding necessary to get the thing moving via remote with stepper acceleration, control smoothing and a wicked-fast 20ms communication delay (by comparison, most first-person shooters operate with a 80-200ms latency). So 1,199 finished lines of code later, I have to admit it's still a work in progress (at least the mechanical camera mounts are) but I'm hoping, at the very least, the XBee and Arduino code involved in the controller and receiver sketches might help out anybody who needs to have super-fast, reliable wireless data communication with error checking and ACK packets using an XBee in API mode.

I'll update this Thingiverse posting with a video of the whole contraption moving under its own power sometime later today once I've had a chance to trim and upload the video.

The latest current source files for the Arduino and XBee powered electronics and the parametric gears can be found at their respective Github repositories here: (for the Arduino code)

and here: (for the OpenScad code)

If anyone has any questions about my code or my tripod, just drop me a quick comment below and I'm sure a bunch of people (including me) will be able to help you out.

This is version 2.0 of a 3-digit, base-10 register for an electromechanical computer I'm working on. It is stepper-driven, and works like a 3-digit counter, counting from 000-999 before rolling over. When all three digit wheels read '0-0-0', 3 reed switches will close and a circuit will be completed to detect the condition.

This one uses fewer parts and has at least been slightly tested. It also has larger digit surfaces for better visibility, and comes with printable labels!

Yo dawg I heard you like picks...so I made a pick shaped box so you can pick while you pick your pick...

Another riff on the living hinge, using it for the sides of a curved box rather than an actual hinge.

A mini digger executive toy. 4 moveable joints, rotating base, 2 arm joints and bucket control from the 2 levers at the back.

These are available as kits through my website.

A minimal approach.

The chargers for all your mobile gadgets lie around you appartment? Well mine do, so I build this box.
You simple put your gadgets on the box and connect them - no more cable mess! (at least until you need to take the charger with you....)

btw: the stars in the holes of the top part are just decoration, I figured I might as well use all the wood, if I'm going to cut it

My hamster needed a new ladder, so I made him one.
If you want to use it you may have to adjust the length or the hole distance for your enclosure.

Laser cutter coolant flow sensor.

The concept was to have a sensor that wasn't inline with the coolant line and couldn't restrict the flow if it seized up. I'm sure that the design is scaleable within reason for other projects. It is simply tywrapped to the outlet end of the coolant pipe and dunked in the coolant reservoir/bucket.
The sensor is a simple hall effect switch.

BTW, if anyone knows how to embed a YouTube link to movie, let me know - the movie is at the bottom :-)

Nikola Tesla's "Valvular Conduit" for your printing pleasure.

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.

For the first time we were demoing our new ToM to a friend, using carefully tested objects, when his son asked us to make us some accessories for his lego viking. Never a great fan of programming as a spectator sport, but I (and my friend's son) were still quite pleased with the results.

This coffin's been tidied up and improved since the demo but still could do with some work it probably could be a bit smaller and it'd be nice to add studs/suckets on the top and bottom (or base and lid), and it could do with holes for attaching things to it, but it's ok as is (and my first upload)

I made a balans chair referring to Varier Variable balans.

You have to prepare
- boards 18mm thick, over 530*500mm
- a CNC milling machine capable of cutting over 530*500mm

Inspiration for this thing came from the Folding Wood Booklet by SNIJLAB found here: thingiverse.com/thing:12707

As soon as saw the Folding Woob Boolket on Thingiverse I knew that design had lots of potential. Around the same time when I found the SNIJLAB design I was searching for ideas to make an iPhone 4 Case and thought this would be perfect.

I wanted the finished case to resemble a moleskine note book and I think I came pretty close.
