About this 3D model

I work with the Pastamatic filament spool rewinder and bought large rolls of filament that do not fit in the Pastamatic, so I built another filament holder However, since I already have several holders lying around, I thought it should be collapsible so I could store it in a drawer, and this is the result Required: 1x 30cm M8 threaded rod 4x 608ZZ ball bearings 2x quick clamps Ø 8mm or 2x M8 nuts
