Shawn & Lara need a Toolbox... Droid?

[kresty]

So, the 300% torque was too much on the D shaft on the motor sprocket.  It stripped them into circles and they slipped a lot.

So, I reprinted those with 2/3ds the teeth, more surface on the shaft, and a set screw. (I had a smaller sprocket designed already, but hadn't used it since the bigger one seemed to be working, but I had to add a spot for the set screw.)

So, now we have only 200% of the speed as before, but 450% of the torque.  It's a completely different beast than before.  Like maneuverable.  Too maneuverable even.

This thing is seriously top heavy.  The tracks can get it over a lot of stuff - as long as it isn't too tippy.  Oh, well. 

Also making a YouTube channel for all the brick stuff.  Having too many droids for each to have their own!
