Ender 3 dual Z axis REMIX freely moving rollers

After mounting the bracket I noticed that the rollers aren't spinning freely anymore, which resulted in severe drag on one side when just turning the Z leadscrew. You could just mount the 2nd Z leadscrew and probably be fine, though I don't think its optimal to drag the wheels along the extrusion instead of rolling. So I made this redesign that allows the Wheels/Rollers to turn freely.
