 Goal is to have a basic version for a price of a cheapest commercial dual-spool drybox. At the time of writing Creality Space Pi can be found on Aliexpress for 366zł.
-I was able to get surplus ammunition boxes for 100zł (~$25). I'm not sure what the best heating solution is yet. PTC heater with automatic shutoff at 150°C and with higher power then other commercial dryers have seems safe. Safer then disassembling a hair dryer. It might be under-powered, we will see. It was cheap, at 52zł. I chose REX-C100 for a PID temperature controller. It's extremely widely used, and it makes it very cheap. 48zł including SRR with radiator and a K thermocouple. Fused IEC socket with rocker switch costs 10zł. I also added optional 2x 220V signal diodes, 7zł. Threaded rivets will make installing ports for printing directly from the box very easy. I got both M4 and M10 from Aliexpress for ~30zł. Convection oven fan with motor is will costs 75zł new, ~50zł used. I opted for a new one named C460002A9. Plus speed controller for 8zł.

Lastly, alarm light/buzzer for 6zł.
-Spent so far: **340zł**. The only thing missing is an alarm light&buzzer - after checking controller voltage.
