Printed an simple bearing this kind in abs... was capable to withstand and easily turn myself so I gave it some thoughts...
not every part needs to be supported...
- 5x11x4mm(IDxODxH) bearings x2
- 2mm grub screws x3
- 10mm M3 socket screws x4
- 14mm M5 socket screws x12
- M5 nuts x12
- nema 17 steppermotor x1
by placing the "small-" and "big rolls" u have to alternate their alignment!!
U could paint the turning part like an UFO (from which it gets its name) and give the motorholder/podest an beampaint or creat one on your own. The licences shall not include the podest! So feel free to change that piece.
