Spool Insert
thingiverse
I came across a spool holder that really caught my eye here: https://www.thingiverse.com/thing:2180428. Since several of my filament spools, which I bought from Amazon, had an inner diameter of 55mm, I needed to find something that would fit that larger opening. The inner diameter of this spool insert is 20mm and the outer diameter is 55mm.
