XY and Z carriage for graphite bushing ( Hypercube 3d printer )

This is a a modified XY carriage and a redesigned Z carriage ( joiner and clamp ) for Hypercube 3d printer meant to replace the typical LMU linear bushings with the solid bushings ( copper and graphite ) with oil impregnated that eliminates possible noise and the maintenance of the axis.
To Greenar request I have uploaded the 12mm OD XY and Z carriage mod.

The bushing 11mm OD can be purchased from here:
