TMR posited it might take half an hour to make a d20 in Sketchup... it took 35-40 minutes, including figuring out a good process.

For the record, I used TopMod to generate the original twenty-face regular solid (it's an icosahedron, I believe, but my memory may be faulty), and I also cleaned up in Meshlab (couple clicks just to make sure the mesh was ok).

It Skeined great, at least for the jumbo size dice.

Do you like to play dominoes but do not have a set of tiles or bones to play with? Then you need this file. Make your own dominoes out of acrylic or wood with this file.

I plan to make lots of these for friends and family in different colors out of different materials. I will use 3/8 inch or 1 cm think material to cut out the tiles. I then will paint the dots with a contrasting color.

My first project was made with a 12 inch by 12 inch (30.4 cm by 30.4 cm) piece of 1 cm think hobby plywood obtained from a big box store of national recognition. The dots were burned into the wood through the rastering or engraving step so no painting was required.

I set the file up so that you could etch, burn, or engrave a logo on the backside and then flip the panel over before making the dominoes. It should register perfectly, but this has not bee attempted yet.

Good luck with your project and let me know how it goes.

This is a derivative of the monkeybot on thingiverse. I made numerous edits to achieve a snap fit so glue would not be required. I added small sacrificial bumps to the "fit" pieces so the fit would be tight. I changed the tail, head and other pieces. I made the cat head version first and as you can see his minions came to his defense. I made a version with fork and spoon for a Paella party we threw this weekend and everyone put together their own forkbot while under the influence of Sangria.

This is a 4-pin tumbler lock with a key and display case. Insert the key and turn clockwise to get a smiley face!

Yet another experiment in TopMod.

This time I really went overboard and I don't think there is a way to print this without adding supports. In fact, you probably need one of those machines that sinters a powder layer by layer... like the CandyFab.

Still, I liked how it looked so I thought I'd share. If this doesn't meet rule number one (a real, physical object that can be made), I'll take it down.

This encoder is made for the RepRap project, but it can be used for any project where you wish to determine angle or rotational speeds. The encoder on the extruder is an important step towards better 3D print quality (constant plastic flow rates).

Note: New Version (Beta 2.1) posted 06/05/2009

New features: 12 legs instead of 8, "drop-in" center platform, 1:1.8 ratio gears, many small changes.

I only update this listing for major revisions of the walker, it's possible there's a minor revision posted at my site that is not here: 4volt.com/projects/jansen/

What you see here is the Jansen walker, a laser-cut robot, based on the Jansen Mechanism. It has 12 legs and scuttles similar to a crab walking sideways. The brain is a Arduino, and the legs are powered by 2 micro-servos modified for continuous rotation.

This project is heavily influenced by Theo Jansen's natural gearing mechanism, it’s a very efficient mechanical leg design for converting rotary motion into leg movements, and is very elegant in my opinion. The basis is the relative distance of the 12 joins, Jansen calls them "The 12 Holy Numbers". The numbers were developed with a genetic algorithm. In a couple of interviews that he wrote the evolver on a Atari STe computer and it took literally months of 1990’s processing power to find the solution.

I've marked this as non-commercial creative commons licensed, but it would be very easy for anyone get me to license a commercial version to almost anyone. For the most part I would just like to make sure I agree with the usage, and make sure I am aware of it.

See vimeo.com/4221721 for a video of the motion.
