I wanted a proper IP65 filament dry box with some good capacity for my 3D printer. There are plenty of DIY and commercial options on the market, but I figured that I would toss my hat in the ring as well. Here it is (the hat)!
This particular design is intended to accommodate 4x 1kg rolls of filament in a 5 Gallon Husky waterproof container, but the same parts could be adapted to any container design as long as it can utilize 3/4in PVC as a spool holder axle.
