DB's Wall Mount Filament Spool Holder

Have free wall space behind you 3D Printer(s) ?
Here is just the thing to make better use of that unused space
Organize and have ready access to your spools of filament
Replace spools without disturbing your whole setup
Using "French Cleat" mounting allows you to easily accommodate different spool sizes
The through holes are for 3mm studding, if everything is glued properly, only the axles will require them
For those with smaller printers, I've split the printing to "Sect" files
