Filament spool wall mount for 32mm tube

Filament spool wall mount which uses a 32mm plastic tube as a crossbar.

I've bought a spool of filament that is too wide for my usual desktop spool holder. So I quickly designed this one to use a 32mm plastic tube I had left from drying box project. You can make the tube longer to fit several spools. I made it so short because I already had holes in the wall from something else.
