After seeing many people using the Commercial Chef model CCD100W6 I set out to make a filament spool drying tray that is stackable, even if stacking on the trays that come with the dehydrator. I have printed and used these trays to dry PETG. I used PETG to print them.

The only downside to this model is that it was designed with Tinkercad so the “circle” shape of the tray is actually a 64-sided polygon. It still works with the trays that come with the dehydrator, should you want to put some distance between the heating element and your spools of filament.

While I have found many “tray extensions” this is a true, stackable tray you can use with or without the trays that came with the Commercial Chef dehydrator.

I used supports in the “tree hybrid” flavor. If you pull the print off the bed while it is still hot, the support is likely to stay on the bed and separate itself from the print. I did Hybrid Trees at 23 threshold angle with no brim.

The trays are designed to be used with the dehydrator's trays to put some room between the spools for better air flow which should reduce drying time.
