This is a parametric solder spool that I originally remodeled for the Pinecil case created by Termiman (which is a remix of a remix of a remix from what I understand). By adjusting parameters within the included Fusion 360 file it can also be easily modified for other applications.

The original spool is glued together, but it came apart easily for me, so I decided that printing it as one piece would be better. I printed a one piece model from Thingiverse, but it broke pretty quickly because the walls were very thin and the layers seperated; I was using filament that didn't seem to have great layer adhesion to begin with. Finally I created this model with slightly thicker walls and so far it seems to be holding together better.

Although I remodeled it from scratch, I did base it on the original spool, so it should look almost identical.

This WILL need to be printed with supports turned on.
