Rostock Max V2 (3?) - spool holder adapter for frictionless spooling

thingiverse

This adapter fits over the wooden arm, providing a smooth cylindrical surface for mounting filament spools. Print at least two small locking tabs and securely attach them to the right side of the cylinder to prevent spools from flying off during printing. Note that the smaller tab may require additional design refinement, such as adding a filleted lip, before it's fully functional. Use with caution until further modifications are made. The larger tab has performed well in testing.
