Prusa Full Bear 2.1-alpha Y motor mount with shaft support bearing

thingiverse

This part is a reworked version of the Y motor mount for Prusa Bear 2.1.0 (still in alpha1 at the time I created this). Check out the original bear mount on @gregsaun / @pekcitron's Github repository [https://github.com/gregsaun/prusa_i3_bear_upgrade/blob/2.1.0-alpha1/printed_parts/mk3_mk3s/stl/y_motor_mount.stl](https://github.com/gregsaun/prusa_i3_bear_upgrade/blob/2.1.0-alpha1/printed_parts/mk3_mk3s/stl/y_motor_mount.stl). It's based on the same concept as published by @sourekv, but tailored for a newer Bear version. This modification adds a 625 ball bearing to the motor mount so that the shaft's end is supported, redirecting some of the forces caused by belt tension, potentially resulting in smoother Y travel. The bearing will require some force to press into the opening and should be possible to extract again without damaging the bearing or printed part. However, it can be a tight fit and success will depend heavily on your extrusion accuracy.
