Had some issues to get the filament down from my drybox to the printer since the drybox sits directly above it. I remixed this to fit the (Un)original Prusa Drybox. The PC-M10 fitting goes through the hole and then in the thread and holds it in place. I used 608 bearings. Since the bearing fit was a bit loose on the original bolt, i added a model “adapter.stl”. It's just a ring that goes inside the bearing. Everything was printed in green Prusament PETG filament. The Ring was just pushed on the bearing (quite a tight fit).
The author remixed this model.
Remixed for the (Un)original Prusa Drybox and added an adapter ring for a better fit of the bearing.
