Is anyone using a peltier dehumidifier in a drybox? (lemmy.world)

I'm reconfiguring my printing closet (~6'x6') for a new printer and thought about enclosing the printer in a moderate sized cabinet (~2'x3'x6' - one "shelf" of the closet) for thermal control. Since there will be inevitable opening and closing, as well as just normal infiltration of the ambient air (usu ~65F between 40-75% RH) it would seem like a good application for a Peltier dehumidifier to keep the RH in the chamber low and reduce my need to re-dry filament which has been on the machine during (inevitable) multi-day or -week downtime between projects.

oh, anything is technically possible. It's totally possible to get a peltier to drive a sufficient temperature delta to condense water at a low dew point. The issue is the exponentially worsening efficiency curve as delta-T increases that would make it's power requirements - and waste heat generation - quickly become untenable for what you're accomplishing.
