drying tower for filament

Tired of excessive oozing and vapor spitting nozzels?
Dry up your filament by putting it into a tower with 2 light bulbs at the bottom. Your printer can draw the filament directly out of this dry tower.

Fresh air flows in through holes at the bottom, gets heated up to 40 deg Celsius by the two 15 watt bulps, the air becomes hot & dry, flows up by your filament, dries it up and through a hole in the top cover, the air can leave the dry box..

Measured humidity inside the box: 20%
Put a wireless temp & humidity sensor inside the box to have control over your filament's environment.

The drying tower has enough space to fit a 2kg filament spool and and 1kg or the smaller 1 pound taulman spools.

The only problem: the dry tower is really huge. A delta printer with 33m diameter built plate is needed.
