Is anyone using a peltier dehumidifier in a drybox? (self.3dprinting)

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.

Which is great if I were storing it and only opening the box for a new roll. I expect to open the enclosure multiple times a day when I’m working with it and the moisture would quickly require recharging. Also, since the box will be accessible for two printers sharing the volume (I might be able to isolate them, but it makes the working space more difficult) and there will be two doors it will be impossible to create it at the budget level I’m considering. Management of moisture, in this case, is a more achievable engineering solution than perfect moisture isolation.
