This is a set of scripts that uses Golly (see golly.sourceforge.net/), a cross-platform cellular automata engine, to create objects that represent the evolution of a pattern over several generations on the Z axis using the rules of Conway's Game of Life.

The scripts generate OpenSCAD (see openscad.org/) programs, which you can use to create STL files for printing.

The demo object represents eight generations of evolution of a glider.

There's been a lot of argument about weapons on Thingiverse lately. Most of it has been folks talking past each other. Can't we all just get along?

So here's a simple flower that will fit in the barrel of your AK-5000 or whatever. Print one out and give it to your local gun collector, national guardsman, armed gangster, or high seas pirate. After all, everyone needs a flower once in a while.

(The flower is from Renosis' super-fun push-puppet.)

So, you've created a sweet rubber stamp to stamp Mitch Altman's awesome hackerspace passports with. Now what? Are you just going to take that thing and hot-glue it to a block of wood? Well, if you're anything like us, probably. But allow me to suggest an alternative-- print out a custom-sized rubber stamp handle, and issue visas in bureaucratic style!

By request, this is the famous, fabulous lampshade script. We've used it to produce lampshades, bracelets, faux ABS LPs, small storage cups, and in any situation where a hollow cylindrical or conical form optionally with a solid bottom is called for.

This script takes an image file as input and produces a gcode file that will create a conical form of the specified parameters, with the image embossed on the surface. It's recommended that you use the -c flag, which will cause the form to be built as a single, continuous spiral.

You may need to edit the script or its output to add your own pre- and post- print gcodes. Be sure to cast an eye over the output before you print!

Printing these forms in clear PLA is particularly pleasing!

The code is maintained in git; the latest version is always available at:

Have fun!

A cleaned-up Stanford Bunny, with the holes in the model sealed.

This is George Hart's reconstruction of a 16th-c. wooden puzzle, currently in the Schloss Ambras Museum. Print out 76 units and reconstruct the original! A full description is available at georgehart.com/rp/torzle/torzle.html.

It's a set of printable Icehouse pieces.

It's replacement Gottlieb C13150 pinball flipper! This is useful for people who need to replace their busted Gottlieb C13150 pinball flippers.

It's everyone's favorite Seleucid-era* toy, just in time for Hannukah! You know the drill: print it out, get some friends together, and battle it out for the future of humankind on this planet**!

(** well, chocolate coins. Still, chocolate's yummy!)

Our foosball table came with the creepiest dead-eyed foosmen possible. Here's a printable modernist alternative!

A hard, printable business card case, perfect for carrying around those fragile, elaborate business cards.

This is a simple hexagonal vase. It's purty!

This is an STL file decribing a Utah Teapot, based on data created by Martin Newell.

This is a pretty poor model for printing; it's been refined by Unfold since:

This is a metaCAD script that can generate simple shaft collars with a slot for a nut and a hole for a set-screw.

This is my first cut at a printable linear bearing for M8 rod. It's intended to be printed by a Cupcake CNC with a plastruder. It will probably take a bit of tweaking before it's ready to go, so don't throw away your precision-machined bearings just yet.

This is a simple design for a swing-away clamp for holding 6mm toothed belts in place. It's not designed to handle very high loads, but should be sufficient for most simple uses.

This is the design for the X-Y stage used in the prototype of the Cupcake CNC robot.

This is a quick sketch for a model of the third stellation of the dodecahedron.

A 2"x2", three-level Sierpinski carpet.

This is a layout for making a 170mm high single digit LED display. I use these to create the digits for my wall clocks. 10 standard 5mm (T1 3/4) LEDs are used for each segments (a total of 80 LEDs per digit).

I've also included a design for a small single-sided board that you can use to easily wire up your individual segments.

Now that I've got these horribly thick business cards, I need someplace to store them where they won't get stained, crushed, or multilated. This simple case made of thin board does a reasonable job.

A calling card with working planetary gears. Astound your friends, frustrate your nemisii.

(Update: I've moved the gears slightly to the right, reducing the number of cut parts to assemble.)

It's a geared calling card! Two slots in the top layer display different information as you turn the smaller gear, and a little window lets you watch the gears mesh.

This is the skeleton for a basic pentapodal robot.

I'm currently using cheap HS-311 servos for all joints. These don't really provide enough torque for the up/down shoulder joints as currently designed. I plan to shorten those members, and get more powerful servos to support them.

A small vase for tiny flowers.

This is a "radiolaria" sculpture roughly modeled on the drawings of Ernst Haeckel. It has simple icosahedral symmetry, with thirty "spines" radiating from the edges.

This is the second stellation of the dodecahedron. Instructions are embedded in the .dxf file. Structurally, this stellation is not as solid as the first stellation, but it's still reasonably sturdy.

This is a slot-together model of the first stellation of a dodecahedron. The slot sizes are appropriate for "172" illustration board, but you can scale the pieces to construct this model out of other materials.
