Want to keep your filament dry while you print, but too cheap to shell out for a dry box? Make your own! My house goes through Tidy Cat tubs at a rapid rate, and they seal pretty well. I was using a PVC pipe structure on the inside, but I think these skate bearing roller stands will work better. Throw in a few desiccant containers and drill a couple holes in the side, and you’re all set! (Humidity monitor optional.)
