Gridfinity Solder Spool Holder

I couldn't find a spool holder that was 2x1 and wide enough for my solder spool, so I made one. this one holds spools up to 39mm wide. It doesn't have magnet pockets in the bottom, I have had bed adhesion problems with them before and since I don't use them I left them out. This also makes the print a bit faster and uses a bit less plastic.

You need an m3 nut and 25mm bolt.
