Standalone spool holder

Standalone spool holder, I think this is one ot the best spool holder for filament. I design it to print in 200x200 bed. Or you can resize it a little.
Holder can be printed all in one or separate.

I print 0.3mm layer hight, with 15% infill (Lines), 3 layers (top, bottom, wall). It takes about 6-8 hours with speed 60-80mm/s.
