Bristlebot Evolution

Modified and printed revisions 2.0 through 2.3 today. Now thinner, motor snaps in firmly, a little less long, battery is snug, wiring runs through hidden tracks underneath, comes up through the battery compartment vertically so inserting the battery does not push it down, and the wire wraps around a post at the top.

This thing has some wicked torque steer. It runs in little 3" circles. Reverse the battery, it runs circles the other way. I'm trying to decide if mounting the motor on an angle would correct that.

I'm also going to play with the idea of using two or maybe even three LR44 cells instead of a CR2032. The 2032 seems to die fast running a motor.

I'll be posting this to Thingiverse when I'm sure the design is settled.
