This is not the most efficient way to make a rigid heddle loom, but it works. There are definitely some parts that need some editing, the heddle needs to be stronger, as do the front and back round beams. Also, the openSCAD files should be parameterized to accomodate any sized loom and heddle.

The loom took a lot of time/plastic to print and I don't expect anyone else to print it, but it was a great way to learn some openSCAD and to combine two of my hobbies.

Toy car with wheels that move, but requires no assembly. Here is a short video:

The wheels took some effort to loosen up after printing, but they now roll quite nicely on the right surface.

Other problems:

There is definitely some warping from the plastic cooling/shrinking (I used ABS).

The transition from the wheel to the axle is a bit steep for the makerbot.
