- 🚚 Steel threaded rivets M10 ≥6pcs.
- ✔️ PTFE tubing & couplers
- ❔ Alarm light and buzzer
- ✔️ Power switch

Cost
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.
Threaded rivets will make installing ports for printing directly from the box very easy. I got both M4 and M10 from Aliexpress for ~30zł.
How to search for parts
Researching products designed for convection ovens (termoobieg) and DIY meat smoking (wędzarnia) helped. There are no unsolved issues here, just a lot of integration.

Ideas for improvements
- Glass visor
- Flament rotation motor
- Humidity sensor (needs to be temperature resistant)
- “IoT” reporting and control
- Load cell for spools
- Klipper/printer integration
