Filament Roll Adapter

I made dry boxes for my filament rolls and had the problem that they didn't fit into the boxes due to the large hole in the middle. That's why I created an adapter for different diameters so that the rollers run centered in the box. The inner diameter of the rollers is for 11.5mm aluminum tubes. The outside diameters are 72mm, 54mm and 52mm. Others will be added in the future.

The threads must be recut after printing. To do this you need a internal and external thread cutter M18x1.5.

Update 12/20/2023: new 52mm Adapter and better threads in all models. You only need to recut the bolt.
