I got 2 spools of inland and a couple i got from a generic brand on taobao, I’m pretty sure both are non-standard as well. The last spool I printed off printables had a really nice table with dimensions for a bunch of different filament brands if you’re curious

I’ll probably take the step and make a couple different variations with different diameters, I have a couple different brands and I’m sure they all have slightly different diameters :D

this looks sweet, will probs try this next time i need a new spool, looks way sturdier than the one I’m using currently
