Hypercube Evolution (HEVO) bed leveling nut knob

cults3d

My small improvement for the amazing Hypercube Evolution printer. Knob for bed leveling. Made in OpenSCAD (source included) - you can modify it as you want it to have. I prepare 2 variants. For M3 and M4 nuts. M4 variant you can see on pictures. M3 isn't tested. You need just M3 or M4 DIN934 nuts. Hole for nut have conus shape. This mean that there is backlash on the open end and you must use screw and press nut inside to the end of hole. There is no backlash inside, hole end is 0.1mm smaller than nut. There is thin barrier in hole. It allow to print it without supports. It must be removed by drill.
