RepRap X-carriage

X-carriage for RepRap that uses two self aligning bushings on one shaft and a 180 degree bushing on the other shaft. This eliminates the need for the shafts to be perfectly parallel and the spacing to be perfect.
See original part for more information on clamps and bushings.
For the 180 degree bushing, use 1/8" delrin dowels such as these: mcmaster.com/#97155A426
