Cryogenically generating ultra dry air for filament drying

[NeverDie]

Filament Drying preliminary results

Just a brief follow-up on the freezer approach. I had earlier briefly looked into using Peltier devices, and then stacked Peltier devices, but didn’t find great info. Well, today a much more informative youtube video on that topic came out: [Stacking 5 Peltier Modules, and Reached -90℃] Still not clear to me how practical it might be, but for a maintenance free approach to drying air it maybe looks promising and possibly even inexpensive.

I had forgotten that I had created this thread as the fork of the original thread, so I should have posted it here instead.
