Transmission shift collar

First thing! printed the transmission here https://www.thingiverse.com/thing:34778thought 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 soonThere'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
