This is an extended axle designed to fit with Hideout Hobbyist's 65mm spacing solder spool holder remix. This remix does not include an extended axle to go with the extended spool holder base so I made one. Just print this axle instead of the original one.
Also included here is a spacer to fit around the spool holder axle and expand the axle diameter to 25mm. This is the perfect fit for my MG Chemicals 1LB spool.
Both of these modifications make the 65mm spool holder much more smooth. Hope this helps someone.
Print 2 of the spool spacers and 1 of the 65mm axle. Then print "Part 2 (Large) from the original inaniaEtVana solder spool holder. And the 65mm solder spool holder base from Hideout Hobbyist.
The author remixed this model.
