Designed for generic 5.8L ricebox with bottom size 195x97mm. Combined dessicant container and spool holder, and fully printable with no need for any other hardware. Just print and use. Despite the shrinkage of the material, it is better to print 1 more bearing to use it's balls to fill the blank on the other 4 bearings. You can also use standard 6004 bearings. The spool holder is not very wide so some thick spools may not fit, less than 64mm width spools shuld be fine.

Additional hygrometer&PTFE hose base model included, it needs some drilling and M3x10 screws - 4pcs to install.

Change log:
9/20/2023: Improved bearing design keeps the balls from falling out; Added 0.1mm gap model besides original 0.2mm gap model for your choice.
