Summary

A remake of the best reusable spool for refills I could find was from car7er at https://www.thingiverse.com/thing:3060389

The original design was filament and time efficient - thank you for designing it! My issue was that it was too small for the refills I get locally (I get Matter3D filaments from BC, Canada), so I adjusted and made a few improvements.

These fit spools up to 80mm inner diameter; and up to 185mm outer diameter.
Adjusted the screw holes to fit M4 bolts on 2 sides. I used M4x20 (2 pcs), but the nut is shallow enough that you could use M4x12 (2pcs).
For added durability and reusability, I've created a way to inset M4 nuts. You will need to pause your print and add the nuts in manually. Screws wear out the plastic over time, so I don't trust not having a nut in there.

Room for improvement:
