Gridfinity soldering spool holder in 3 versions:
All have a 2mm guidance hole for the solder wire to pass through.
Can be printed without supports. You do not need any other hardware, the spool holder parts screw together. There should be more than sufficient clearance built into the model for this, if it is still too tight, try an XY hole compensation on Spool Holder Part 2.
