Filament Dryer, this is a quarter of the filament dryer housing designed to fit on print bed (size 161x159mm) and clip together, so you will need to print four.

For 320mm and 280mm Diameter Food Dehydrator.

I made two version of each 130mm and 65mm high.
65mm version can hold 1kg spool (65mm wide) or 0.5kg spool (43mm wide)
130mm version can hold 2 x 1kg spools or 3x 0.5kg spools or 1kg and 0.5kg spools.

You can also stack these together.

Due to size limit in Tinkercad I had to scale this down by a factor of 10.
You will need to scale up in your slicer by 10X or 1000%
