Kossel Mini Carriage - 20mm X 15mm

This carriage fits on linear rails that use a 20mm X 15mm bolt pattern. 20mm wide and 15mm long (parallel to rail travel). Arm mounting width is 40mm from face to face, base to center of arm mounting is 8mm, belt lock is GT2. All holes are made to fit M3 screws.
I have not tested this yet to check clearance, I will be printing and testing them shortly and possibly modifying model if any clearance needs added for arm travel or for the belt to move through.
