Summary

Another stand for your roll of solder. It is a better version of https://www.thingiverse.com/thing:3880406. No idea why I let the top open there, but it was annoying after 3 years :).
It has two mounting points and two solder guides if you want to use them.
The axis snaps into the holder by bending the two stands a little open.

Comes in 4 sizes, 25 mm, 30mm, 35 mm (picture) and 40 mm.
A STP-File is added so you can relative easy adjust the width of the stand

Happy soldering :)

Look for a third hand and more tools and the like here:
