Filament Box Holder

Filament Box Holder, due to printing size limitations, it is assembled from multiple parts, but the connections are not loose. The storage box used is 40.5*31.5*23cm, with an inner diameter of 35*25.5*21.8.

The matching bearing is 608zz (inner diameter 8, outer diameter 22, thickness 7mm). The frame sides and back part are designed for expansion to hold a hygrometer and desiccant, and have been shared and uploaded. It is currently in use and functions normally, but the rollers do not pull the filament. During bmcu use, it was found that repeatedly pulling the filament back and forth when changing it can tangle the filament line. Originally, I had the filament going upwards, but later changed it to go downwards to pull out the filament, which is relatively better. Since I've only been using it for a short time, no other issues have been found yet.
