I have been working on this video in the background for months, and I barely got it together before no effort november.

So let's learn about freeze dryers and how bonkers it is to own one (in my opinion, anyway)

I bought a freeze dryer so you don't have to

@TechConnectify I wonder how well this maschine works to to dry 3D printer fillament
@Martinius That's a great question! I don't really know the mechanisms by which filament takes on moisture, but I don't know why it would at least reduce it.
@TechConnectify @Martinius People definitely use small domestic dehydrators to dry filament. Damp filament prints badly because the moisture boils as it’s extruded at ~200°C and ruins the finish and integrity of the print. You can tell if you have damp filament because it crackles as it prints.
