Finished up my design for the enclosure. It's decent size, and while I'd considered breaking it into a couple of pieces (minus the obvious lids, etc.) it fits neatly on the bed of my CR-10s, so I opted for keeping it in one piece. Normally I tend to print these types of things in an exciting color, like black or gray. With this being both a large print and something that's more akin to a consumer appliance, I decided to buy a roll of filament just for it (Cura says it should take just over half a roll). Opted for a dark green color; once it arrives I'll start printing and hopefully not to long thereafter the PCB will arrive.

In the meantime, I went ahead and printed the control panel piece. I opted to do so with translucent filament as the PCB will be underneath it: I'll use the integrated LED on the ESP32 to give me the status of the WiFi connection and it's also the part of the internals I wouldn't mind showing off a little. You can also see in the background that I printed a test piece for the fan/heater mount; glad I did this as I ended up tweaking it a little to make sure it fits well in the final print.
