3DQF Filament Spool Side Wall Replacement

While I enjoy using 3DQF filament, I find that the cardboard spools are that durable.

I designed this side wall replacement after one of my PETG spools became unglued due to the filament drying process in a food dehydrator.  

I've printed this with .30mm layer height and with Prusament PETG.  

The part will attach directly to the spool core, it's better to print it twice and replace both cardboard sides entirely in order to keep the symmetry of the spool.
