Filament Holder End-Caps
thingiverse
A set of heavy-duty sandwich-style end-pieces for making a filament spool holder out of a tote. There are options for 1/2 and 'full round' pieces plus the back-side caps. I printed them in PETG @ 25% and they are ROCK Solid. - They hold a 30mm 'Closet rod' and were set @ 32mm in the Fusion 360 model I made. - They use are designed to use M4 Hardware but the thickness around the holes means you can probably drill to use M5 without weakening them.
