Customizable Folding Filament Spool

An easy to use folding spool. I made this because I often use filament that comes in a coil, but when I print with it I prefer to have it loaded onto a spool. Manually winding filament from a loose coil onto a large spool is very tedious and annoying work - I'd much rather be designing and printing stuff instead!

So this spool will let you quickly load/unload a normal loose coil of filament for printing.

Customizable in case you want to have a larger or smaller spool for other purposes
