Remix of Ichibey's Sakura Cube design. I'm using it for a CoreXY printer but it's also compatible with H-Bot gantries.

Includes 44mm X-rod spacing version to match the Sakura Cube and 70mm version to match Replicator carriages.

SKP files attached if you want to edit.

Goes with matching motor/idler brackets:

Designed for 8mm linear rods. Needs some misc M3 hardware as fasteners and 623 bearings for the idlers. Stack bearings with M3 washers to centralize them.

44mm version fits standard LM8UU bearings.

70mm version can use LM8UU or LM8LUU (extra long) bearings.
