Gridfinity solder wire holder

Bottom part generated using the excellent gridfinity-rebuilt-openscad by kennetek (2x2, height 1, holes for magnets). The rest is from Freecad.

Pin fits solder wire spools with holes larger than 10 mm. Slot in place from top and rotate 90 degrees to lock in place. Prints ok standing with a brim and without support.

Spools with a diameter up to ~65 mm should be ok, unless the hole is very large. Maximum spool width ~70 mm or several smaller ones. Prints ok without support from PLA with 25 % infill.
