spoolmaster v2.0

One to spool them all... more or less.
A spool holder that is compatible with spools from 16cm (300g) to ~30cm (5kg) in diameter. I've been using the previous version for four years now and it never failed me. Features are:

- concave roller shape to self-center the spool
- no tools required for assembly
- wide stance feet to prevent accidentally tipping over
- sturdy and long-lasting
- totally over-engineered
- beautiful (results may vary)

What you need for a complete spool holder:

- 2x inner wall
- 2x outer wall
- 4x foot
- 4x guide roller
- 4x 608 type bearing

You can use the modifier meshes in your favorite slicer to save filament and time by removing top and bottom surfaces and just printing infill.
