Voron Design standard spool holder modified to fit into Ikea SKÅDIS pegboard.
No need for bearings or anything else except standard PTFE (Teflon) Bowden filament tube to minimize the friction so spool can rotate easily.
Should be simple to print, but requires some small support to hold the hooks.
Recommended printing material is ABS, but others can be used as well.
Note: I had to sand with a file just a bit to get hooks into the holes and it is tight so it does not move, which I like.
Let me know how it works for you, thank you.
Updates:
TODO:
Larger holder with reinforcement, possibly to hold more secure large spool or x2 normal spools at once.
The author remixed this model.
