Original part idea here:

Saw their video on YouTube and really liked this part. Only problem was that it was a bit of a pain when I needed to switch spools. Decided to put some slots where the filament tube guide goes so that it can be easily removed if necessary. Just pull the tube guide out of hole and slide out the filament!
