Spool holder rotor with bearings
thingiverse
Spool holder rotor with two 608 bearings. Designed in Kompas-3D software, for those who use it .m3d files are attached. Don't forget to add spacer between the bearings, because AXIAL LOAD MUST NOT BE APPLIED TO RADIAL BEARING. Just imagine Bart Simpson writing it down the chalkboard at Simpsons opening :) I used precisely cut piece of 10x1 aluminium tube, you can easily print something like this, center hole has 16mm diameter. Axis is piece of M8x1,25 threaded rod, slim nuts are holding and fastening it, winged nuts are holding the whole assembly in spool stand.
