About this 3D model

Snap together Spool Holder - No extra hardware required! I was looking for a spool holder that I could completely 3D print, was stable and I could easily swap out the Filament rolls. I couldn't find one already made so I made my own. I didn't want to use screws or nails, or bearings. It took me 4 versions to tweak it just right. Now I just drop different rolls of filament onto my spool holder. I even store my filament rolls with extra spools with the connectors. The large spindle is 50mm The small spindle is 30mm YOU MUST PRINT THE EDGE CONNECTORS FOR THE SPOOL WITH 100% infill.
