Based on Sandy Noble's Polargraph: http://polargraph.co.uk

This is the first pass at a printable gondola for a Polargraph. It works, but it could use some tweaks.

Anyone looking to improve it: the lower section arms are a little thin, and the spot for the captive nut isn't exactly sized right. I'd also beef up the upper chain mounts, as there's not much plastic outside the hole.

The motor brackets and pulleys I'm using can be found here: http://www.thingiverse.com/thing:12403

Print it out, no assembly required. Uses an M3 bolt to adjust the grip on the pen, and another to mount some kind of weight on it. You could use washers, I used quarters with holes drilled in them.

Super awesome. What kind of stepper motors and microcontroller did you use? Shields?

Hi there! Question : which motors are you using? I coudn
´t find any motor matching the specs (0.9 degree resolution, 0.6A ) Please help! :-D

AWESOME. I've been thinking of building a plotter like this for a long time. Your design is so simple, just great.

Excellent design, you've inspired me to make a polargraph myself.

Think there's a problem with the STL file, though. The two arms don't seem to slice right and ended up completely detached on my print.

Ok, I get errors when I slice it, but it still works. It's because of a problem with the holes in the 'chain mount' sections. Not sure how to resolve it. It still printed fine for me. I'm working on a new revision anyway.
