This is a remix of a model I found on Printables that allows you to screw in a pc4-m10 Bowden tube so you can feed the filement into your printer FROM the food dehydrator.

Link to the food dehydrator I am using:

You will need a spindle to keep the filament in place.

I have designed one you can use:

You will also need a minimum of 3 (you can stack them technically) of these to complete your loop:

approx 301mm diameter food dehydrator.

I printed in ASA but you can print in other materials if you think they will hold up to the heat settings.
