About this 3D model

I got tired of using spool adapters that didn't quite work so I combined the best ideas from what was out there into my own design. If printed correctly (check out the 3mf files) these are quite strong and will not slip due to the ribs. Confirmed on: Generic [200mm], Overture, eSun, Inland, Polymaker, Printed Solid, and many others. Printing these using a matte PLA will provide better grip. I prefer Polymaker or Overture . Updates 2025-05-19 Redesigned the adapters to print quicker and be stronger. Ribbed version is no longer supported as it weakened the model for no real benefit. Several versions are included to fit more spools (-1.0, -0.5, +0.5, and +1.0). Added text to indicate the size of the adapter. Added the Fusion file if you want to create a different size.
