Filament dry box with rollers

This is a import of my model I previously published on printables. Summary Variation of the filament dry box with ball bearing mounted rollers. Differences of the remix compared to the original This base uses rollers like these classic “open air” filament rollers. 4 608 bearings are required. I would recommend to use smooth running ball bearings. Some of these cheap ones from aliexpress introduce quite some friction. The base can hold spools with a width of up to 74mm. No idea what the maximum width is that fits in the actual box. Likely less. There are 2 Versions of this base available. I am using the “low” version. With some spools there will be some space between the spool and the Top part (with the humidity sensor). The “high” version should fix this, but i never printed this version, so no guarantees.
