This Spool holder was inspired by Fishing spinning reels, they are the reel with the least amount of friction. This was replicated with my design. It holds the spool at a sideways angle pointing towards the top of the printer where the filament will go in. With this design there are no noisy moving parts. You can also adjust the height for larger spools with the extender. This spool holder is simple and elegant with less friction than other designs.
I hope you enjoy my design:)
place the inner rim of the spool on the L shaped lip, and point towards where the filament feeds into your printer.
