100g Spool

Disappointed that other small spools were quite heavy, this one weighs about 15g with 20% infill (Cura estimates 17g).
Shrunk down the LMSR v2 (peg slot still has the same size), and removed the rim and got this.
Photo shows about 90g of filament wound up, I'd guess that with careful and neat winding there is a non-zero chance of getting 200g on it, but I haven't tested it.

For some reason the original is gone from thingiverse but you can find it if you google for "Little MasterSpool Roller V2.0"
