Hypercube CNC-Drill Mount - 36mm

Just something, i've thrown together in TinkerCAD - not testet yet, since i'm currently collecting all the parts needed to build my own HyperCube.
This mount is supposed to be used with this or similar ⌀ 36 mm motor: https://www.banggood.com/EleksMaker-555-Spindle-Motor-Replacement-Parts-for-EleksMill-CNC-Engraving-Machine-p-1200832.html
