I recently bought a Silvercrest food dehydrator to dry my spools of PLA and PETG. Given that I had a lot of desiccant beads that needed regenerating, I was keen to use the dehydrator for this as well.
After a quick search, I found BaconFase's Food Dehydrator Tray Mesh; however, I wanted multiple individual trays instead of a mesh that covers the whole level of the dehydrator.
The solution I came up with is this simple mesh tray. Each level of the dehydrator will fit 4 four of the mesh trays.
Print with 0.3mm layer height and no top or bottom layers.
Material: PETG (You do not want to print this with PLA as it will get soft in the dehydrator)
Infill: 35% rectilinear (Important! The infill is the mesh)
I have added the Fusion360 file used to create the tray. It has parameters that should allow the tray to be adjusted to any round food dehydrator.
When I was uploading this model I found a very similar Dehydrator Desiccant Tray from jshessen that was created with OpenSCAD. If had seen this before creating my own model, I would probably have used that.
