A shelf extender for the Commercial Chef CCD100W6 (and possibly other dehydrators) to accommodate filament spools. This one is split into two pieces that nest compactly for storage.

There are two 4mm holes that allow a reverse Bowden tube so that you can print directly from the dehydrator using my Horizontal Filament Spinner for Dehydrator https://www.printables.com/model/276017-horizontal-filament-spinner-for-dehydrator.

To help determine whether it will fit your dehydrator, check if the inside diameter of the top of your tray is 236.5, and the outside diameter of the bottom of your tray is 234.8.

Note: model is 278.2mm across so it requires a fairly large printer. I haven't tried breaking it into pieces; it could be challenging to glue together.
