Modified Rostock Mini Pro Carriage

This is a modified version of the Rostock Mini Pro carriage adding a second pair of linear bearings in order to make the carriage sturdier and remove any play.

In my case, with the original carriage, it would wiggle quite a bit when you moved it up and down. With this mod, this play has been removed. I also enlarged the holes for the zip ties, so you can fit 3.5mm wide zip ties.
