Filament Screw Clasp - Use filament as necklace!

I made a very simple clasp mechanism that can be used to adapt 3D printing filament for necklaces and bracelets. The claps is composed of two parts, which are both glued to the ends of the filament. The closing mechanism is composed of a screw and a bolt, with the screw being able to freely rotate around the filament to avoid tangles. The screw part prints better horizontally (for strength) while the bolt part can be printed vertically. I tried both PETG and PLA: PLA produces cleaner result
