Thru plexi spool hanger

Storing my filament inside the enclosure and needed a way to mount more rolls. This keeps them dry as well. 45mm x approx. 40mm diameter. Should fit most spools. The bolt is 25mm diameter so a standard step drill bit should be sufficient to drill the hole. The threaded shaft is 25mm long or 1 inch. I made it long enough to go through ply board as well. The cuts and indentions were an attempt to reduce the amount of material used.
