Dry Box Filament Spool Rollers with Hygrometer - Prusa Mini Compatible!

Click the links for Bill of Materials The original model wouldn't fit on my Prusa Mini, so I chopped off an end and modified it to fit a little less expensive hygrometer. You can still add desiccant to the tray for a proper dry box, but I recommend putting it in stainless steel shakers so that you can easily flash off the moisture in an oven every so often. The model requires 608 bearings.
