It's too easy to think that a laser cutter has an infinitely thin beam. It doesn't. Depending on the material, speed, power, we've found an "effective tool diameter" of 0.002 - 0.008 inches.

This hole gauge cuts and labels 100 holes, from 0.050" to 0.149" in a 3 inch square pattern. When cut into the material you are using it can tell you EXACTLY how large to make body or clearance sizes for various screws and rods, and how large to make tap holes for self tapping.

The sizes will cover hardware from 0-80 to 6-32.

There are many snowflakes, all alike, all different.

Some are thermodynamically generated, some algorithmically generated, some are also recursively generated, and some are even made by hand.

These are for you to use.

Revised design 0006 will no longer put pressure on the X stage.

End stop triggers are important! They should be fastened securely, no jam the optos, and allow for precise positioning at every new built.

These stops are designed so that the Z stage can travel below the build platform, calibrating the Makerbot for a repeatable distance between extruder and platform. This is done by setting X to center and Y all the way to the left. The extruder now misses the build platform, finding its calibration. A calibrated Z stage will bring perfect results at every build without manually positioning. Software will follow.

This is a complete set of six end stops. All six end stops are designed to fit right into their respective places. They are wedged for easy fitting into the existing slots on your MakerBot. All end stops should be a tight fit. They are designed for minimum interference with the system and should not jam the optocouplers once the are bent right.

A python script to generate OpenSCAD models to generate two parts of a box that screw together and snap fit if you find your way through the maze :)

Reproduced from a wooden burr puzzle given to me as a gift. The two-part pieces are my own design that snap together when assembled as part of the puzzle.

These are laser cut seed pod holders for a homebrew aeroponic setup I'm building. These should in theory fit an AeroGarden SpaceSaver 3 or 6, but as I don't have one to test with I'm not sure.

More details on my DIY Aeroponic setup are on my blog, kellbot.com

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.

Simple Christmas Angel. My Mum used to paint wooden ones, so I've done my artistic take on the Christmas Angel. There is a loop on the back of the head so you can either stand it up, or dangle it from a divine thread.

This is the second half of my openscad.org gear sets.

I couldn't get the top and bottom parts of the double helical to union properly, so I ended up offsetting the bottom piece by 0.1mm :( It skeins and prints fine though.

This thing is part of a set:
- spur gears: thingiverse.com/thing:1336

UPDATE: I'm printing some gears and noticed a couple mistakes on the openSCAD script: the variable 'orientation' wasn't doing anything and the value 'extrudeInDiam' was in fact being used as radius. They're both fixed now and I uploaded a new version of the script.

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

Voltage regulated tea :)

I couldn't get the typical tea infuser holes to print nicely (too small), so I used a different approach: a large hole on the back covered by a grid that lets the water in and out while keeping the tea leaves inside.

A box that screws in a zigzag way. Python generated OpenSCAD model.

Since OpenSCAD does not support variable reassignment and recursion I wrote some python glue code to generate OpenSCAD models.

Now we can haz Turing Complete Models :)

There is an improved version of this available: thingiverse.com/thing:1414

All the world is a theater and you, with shades, will riff upon it. Seeing the humor in things is sometimes a matter of the company you keep. Laughing at all the world's ills becomes so much easier with Mike/Joel and the bots along for the ride.

You know you want me, baby!
Take a look at some photos of this thing in action: flickr.com/photos/gianteye/sets/72157622837429705/

So after making the fully printable hinge, I was able to move along with making a hand. Its got all of the degrees of freedom as a human hand. Its a bit bigger then a normal human hand, therefore its evil.

All parts total was about 10 hours of printing.
