For spools with outer diameter of 198mm.
Inner diameter of the rims are 197.6mm - makes for a tight friction fit.
Tested with 1kg of filament and works perfectly with no issues ever since installation.
Consider using hardware such as bolts or nuts in the core if you need the spool to be weighted down more.
Print all 3 pieces
Holder piece and Cover piece can be printed normally.
Use the .3mf file for cap piece. This will create hexagonal holes on it.
If you need customization to fit your specific spools exactly or the working files, please leave me a message.
