I found @GunplaMark_876550's Filament Dry Box with Rollers and really liked the concept, except that there was too much resistance in the roller system, especially with TPU, and would cause under extrusion. I then found @tcosta_240835's remixed Modular & Minimal Filament Drybox which had much less resistance, but required printing a bunch of different spool holders for different brands.
So I made this. It uses the same standard 7.5mm x 22mm skateboard bearings so spins very easily and fits within the 73mm clearance of @tcosta_240835's stand. I designed it to work with a wide range of spool width and hole diameters. I made sure it fits the following brands that I print the most, and it probably fits most others.
| Brand | Diameter | Large Diameter | Width | Offset |
| Elegoo | 52.5 | 65 | 0 | |
| RED | 54 | 56.5 | 0 | |
| Amazon Basics | 54 | 82 | 62.5 | 5.5 |
| Tinmorry/Eryone | 54.5 | 83 | 62 | 12 |
| NAGA | 59.5 | 73 | 58 | 5 |
The threads were designed with extra clearance but the bearing holes are exactly 22mm, so I recommend using X-Y hole compensation based on your printer, 0.15mm worked well for me. I also recommend printing this in PETG due to its low friction and flexibility/durability.
