The diameter of the food dehydrator is about 275 mm, I didn't found any model that fit my dehydrator so I made my own.
You'll need a fitting pc4-m10 for the filament exit and some PTFE tubing, all panes are joined using some zip ties.
You have 2 options for the filament exit pane, no supports needed, meant to be printed upside down and with a brim.
The author marked this model as their own original creation.
