Needed as soon as possible a spool holder for larger spools so printing anything that is dozens of hours was out of the question.
Solution? Looked at the heavy shelves and had an idea.
One remix later, a 1-hour print and with some round wood that was lying around this spool holder was born.
I like the position of the spool so much that it is here to stay.
Surprisingly very low friction. The only issue is it slowly grinds away the wood but at this rate, I will have gone through dozens of spools before the wooden rod needs replacement.
Maybe add some lubricant? Something like chain grease for bikes should work fine and keep the wood from eroding. Just check how it interacts with plastic or it might eat your mount point instead :D
Graphite (even just shaded on from a pencil) works quite well for wood. I prefer the stuff you can get in a powder.
Wax would probably work.
