$5 Five Dollar Filament Spool

This spool is designed to securely hold spools of $5 Filament from ProtoParadigm. The halves screw together.

This was inspired by another design I saw, but wanted some changes, so I designed this from the ground up to use less plastic, have space for bearings, and have thicker/stronger walls for the threaded areas.

This calls for standard 608 bearings for a smooth, care-free glide.
