This is my entry into Joel's challenge for a spool holder that he can hang on his huge filament wall.
I made into a modular system, this way each part can be printed in the optimal direction for strength. As well that broken parts can be replaced (fixed) easily.
The bar part of the spool holder can be varied in length so that Joel can fit different sized spools.
ps. print in pictures wher printed with wrong printer profile and there for not the best quality, my apologies.
There are 4 different variations of the part(bracket) that clips on the wooden bar.
2 versions that do not need supports, however these are not as strong as it counter parts.
2 versions that do not have the lower flex bar incase Joel ever upgrades his system or that he prints them in a filament that does not flex enough.
