Filament Dryer Box for Print Bed

More of a test than anything. I needed to dry my orange pla to make halloween stuff that was strigging like crazy in my last prints. 

I do not own a filament dyer and I remember I saw a vid on YT that provided good enough results with that solution> drying filament using the the heated bed of the printer.

So here we are. I did that 215x215x140 box with some holes on top. It's enough to fit two 1kg filament spool. 

It has been running all day and maintains 37C at 31% Humidity inside the box (bed set at 55C and outside is 26C at 65% humidity).

I printed in Low Quality, accelerated my E3V2Neo to 75mm/s and it took 14h to print give or take. Results are good. Walls are 2 line wide.

(+ I wanted to print something covering the whole bed to check adherance of my print and all ok)
