Telescope Worm Drive

There are three part designs here. Each might be useful on its own.
Motor Bracket
Motor Coupler
Pillow Blocks

The Motor Bracket is my first 3d design (yay me!). It requires some minor sanding to get things to fit. Need to learn to not call things so tight.

There is a coupler for a stepper motor to a 5/16 threaded rod. The rod end needs to be tapped since it has no threads (my modeling skills are up to making threads yet). This is destined for my telescope mount.

The pillow blocks hold skate board bearings. The fit for the bearings is a little lose but the nuts hold everything in place so all is good ;-).
