The file 'Spool Refill 80mm Dia 3D Printer Model' is (stl) file type, size is 167.5KB.
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 big to fit the refills I got locally (I was trying out the refills from Matter3D here in BC, Canada), so I adjusted and made a few improvements.
These fit spools up to 80mm inner diameter; and up to 185mm outer diameter.
I've 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).
Room for improvement:
Hope someone else finds this version useful!
