adaptor for Dörrex dryer - 9kg spools

New Filament contains often too much humidity, even if it comes out of the box.
You'll notice then the extrusion expanding immediatly after leaving the nozzle.

If more water is contained in the filament, you will also see the nozzle spitting out vapour clouds.

This is because the water in the filament becomes vapour. The vapour foams up the extrusion.

Instead of putting the filament spool into an oven, where the temperature is hardly controllable, you can use a fruit dryer. A fruit dryer is a kitchen aid that cotsts around 100 Euro.

The temperature can be set to 40 to 70°C.

The problem: a 9kg Filament spool is waaaay bigger than pieces of fruits.
This is why you need this adaptor and housing. Put that on top of the dryer your spool fits smoothly.

If you add two 10mm metal axes and 8 bearings (22x8x10) you can also print while drying.

This adaptor housing fits the fruit dryer "Stöckli Dörrex".

for PLA don't set the temp to above 55°.
PETG is fine with up to 60°.

Drying of a 9kg spool takes 20hrs or more. Leave the 9Kg spool for in the box for drying before you start printing.

So if you by such a fruit dryer, take one without timer, as the timers allow only up to 10-15hrs drying.

Use PETG to print this, due to better temp resistance.
