Cardboard Filament Roll Insert for Prusa Core One MMU3 Community Spool Enclosure

I made this simple small insert so cardboard filament spools will fit in the Prusa Core One MMU3 Community Edition (https://www.printables.com/model/1295332-prusa-core-one-mmu3-community-version) stock spool holders. I found that my Overture spool center was slightly bigger than the Prusament spool center, causing it to drag on the bottom and not spin freely. I made this insert to solve that issue and it works great.

It may take a bit of force to actually insert it into the spool, it's designed to be sturdy and/or a tight fit so it can properly hold the spool in the older since all of the pressure will be on the insert.It may take a bit of force to actually insert it into the spool, it's designed to be sturdy and/or a tight fit so it can properly hold the spool in the older since all of the pressure will be on the insert.

NOTE: This was only developed and tested for Overture cardboard spools (https://www.amazon.com/OVERTURE-Filament-Consumables-Dimensional-Accuracy/dp/B07PGYHYV8), if this doesn't work on your spool, feel free to leave a comment and I'll do what I can to make one that fits. Alternatively, feel free to take my model and edit it to fit your spool as well :)
