Caveman Spool

IMPORTANT: I added an angled winding if you don't mind potentially ruining the filament. I wanted this to be functional as storage for the last several meters of a spool which is why the default core has rounded edges.

According to science, this is how the cavemen from long ago (late 1900s) would wind their filament. This was surprisingly annoying to wind. And without through-holes to hold filament, you have to purposely tangle the filament to keep it taught. Can't believe this is how things used to be.

Anyway, 0.30mm layer height for everything is fine. You can use filament to hold the stone slabs to the winding core if you want.

Also, the slabs are unique. I was tempted to just mirror the slabs but I'm not that lazy. Also, since I'm trying to mimic cartoon stones, it helps to have as much assymetricality as possible.

You can use two of the same slab if you want, since their “interfaces” with the core are identical.
