Wall Mounted Filament Spool Rack

I created this after looking over

MothersOfInvention - Filament spool holder
https://www.thingiverse.com/thing:3139782

and

Atu's - Wall Mounted Spool Holder (Stronger version)
https://cults3d.com/en/3d-model/tool/wall-mounted-spool-holder-stronger-version

However, neither really worked for my needs. I used parts from each to build this. I wanted something that used bearings but also needed to be wide enough to accommodate 4kg and 5kg spools of filament. There are three different axles (Regular, medium and long) and two different length mounting arms included for this reason.

It uses 8mm x 22mm x 7mm bearings. Like these: https://www.amazon.com/Pack-608-2RS-Ball-Bearing-Skateboards/dp/B07C6FL8TW/ref=sr_1_8

I did have to put a piece of foam behind the spool as a slight brake or the spool would continue to spin!
