First thing!

printed the transmission here https://www.thingiverse.com/thing:34778
thought it would be cool to get it to just turn slowly as a display, had an extra stepper chillin on my desk and went to it!

So here is my shift collar/stepper spline drive shaft! Its a 2 piece print in place axle. the outter shaft selects the gear and the inner shaft connects the motor, if successfully printed, they should slide freely but not separate.

The motor mount/stand isn't finished yet, coming soon

There's a support cone i used to help stabilize it during printing. printed the shaft at 100% infill and the cone at 10. it has the same tolerance as between the inner and outter shaft
