DRYBOX are nice, but there is a lot of force on the extruder to unwind the filament, and it caused me a lot of failed print. I modified TUSH - The Ultimate Spool Holder, to fit into the DRYBOX offered by Ondřej Stříteský, the spools unwind better now, and without noise.
You have to print 4 of each STL, and glue two part of the spool holder together, fake bearing go in the place of the originals, Bearings and rods are the same as the original dry box.
It is compatible with Cover for silica container in dry box by Tilan2000 ( https://www.prusaprinters.org/prints/66349-cover-for-silica-container-in-dry-box )
I used PETG with 0.2mm layer height
