Rigid Universal Filament Spool Roller Stand (RUFSRS)

I have looked at many spool holder systems and liked none of them so I designed my own.

This Spool holder is fully universal and pretty damn rigid. Walls are all at least 5mm thick,708 Bearings are held on by M8x30mm bolts But M8x20mm should do.

The bearings have an idler/caster that is a rounded V shaped which allows the spool to self center. This also allows the base to be free standing (IE you dont have to bolt it down)

If you prefer to bolt everything down Each foot has 4 M3 mountin
