About this 3D model
Ever since I upgraded my Prusa mk3 with a "roller-style" spoolholder, I had the issue of Proto-Pasta's cardboard spools getting dented and then "derail". This simple spool guard designed in Fusion360 protects the cardboard spools by its slightly greater outer diameter. The edges are rounded to stay securely on the rollers. Both Parts have long threads so the width can be adjusted freely (min 40mm to max ~80mm) to accomodate all spool sizes. In theory, this design works aswell for any other 200mm spool.
