This is a modified Hypercube Evolution Carriage. It should fit a setup with 10mm carbon tubes and 19mm bearings on them.

i didnt like the tightening of the belts in most versions so i added those angled holes. put the belt through them and the GT2 Belt Negative should hold it (put a long M3 screw through it and a little M3 insert nut).

i was only able to print the GT2 Belt Negative with simplify3d - cura made the walls to thin - and there is not much wall anyway.

various versions of the negative are added - depending on the printer, fillament etc. its necessary to try out which hold the nut insert the best.

works nicely on my printer - and tightening is easy. one downside still is holding the belts on one side with zip nuts - will be changed to some screw down part. (holes/nuts are already there).

The Fin at the top is for another part that makes a piezo Z sensor possible.
