After purchasing a couple of 10 m filament samples I had the need for a spool. I couldn't decide which one to print but wanted the spool to fit to the holder of my Makergear M2, so I made my own.
Trying to get it lightweight but with a large inner diameter it came out a bit organic and with a certain amount of alienness. I like it so I decided to share, knowing well that there are far too many spools already and the world is not waiting for mine.
My print from white PLA weighs about 55 g and is quite sturdy.
I included the OpenSCAD File in case anyone wants to play around with it.
