PolyMegaDryer

Upgraded version of a Polydryer with a 400w PTC heater, 7530 blower fan and controlled by a STC1000 temp controller. I tried printing it in ABS but that became soft at higher temperatures. So I decided on printing it in Fiberon PET-CF17 which have no problems so far. 
 

Top cover is screwed in place with M3x8/10/12mm screws. I tapped the holes beforehand.

Please remember that the Polybox only withstand up to 70c - so keep it at that as the highest or below that. Also for your own safety do not use it unattended. As for s safety feature a thermal fuse could be installed.
