75mm Spool Shim
thingiverse
The spool holder designed by gspence on Thingiverse, specifically https://www.thingiverse.com/thing:2135132, perfectly suited my needs, but unfortunately proved too small to securely latch with my Sunlu filament spool, which boasts a 75mm center hole. This custom tapered shim expertly reduces the hole's diameter to approximately 60mm, allowing the spool holder to function as intended.
