Air leakage isn't an issue. Based on the enclosures I already have they do a pretty damm good job of keeping the nasty ABS fumes inside.
Just quick math but I should be able to do it. Given that a lot of enclosures can reach 40-50°C without active heating and insulation I guess 70°C passive is realistic when you do 6cm of XPS. I probably will go with an overshoot and cool down the air for the temperature control approach.
Big & bulky isn't an issue as the stock printer is already big and bulky with lots of space for insulation (originally used for the 4 filament spools but they live in a dry box so it is free real estate): The printer already has 60mm extrusion I can fill up with so no additional bulk is added. The bottom plate will be 2cm to keep as much print volume as possible in the z-direction. Maybe I can squeeze also 5cm there with some 3D-scanning and milling pockets.
Some heating or cooling is required to keep it stable. Don't matter if you need heating or cooling just something for regulation.
The enclosure for the other printer is slightly more complicated as I am aiming for a 150°C chamber temperature (135°C is required) there which means stainless steel or aluminum inner lining and rockwool insulation that can't be milled to shape like XPS.
Half the fun is pushing limits and seeing what works and what doesn't.
