Samla quick change airtight filament storage 22L

I created this make a filament storage that can easily be changed and doesn't depend on spool size (diameter and width).
You simply drop the new spool in and, if necessary, adjust the width of the bearings. DONE
I added M6 couplings to guide the filament straight to the extuder.

You will need:
Ikea Samla 22L
2x M8 325mm
608 bearings (4 for each spool)
M8 nuts
M6 coupling

I used these to seal of the ends that are not in use:
