Dry Box System

thingiverse

This is a custom dry box filament feeding system of my own design. To build one, you'll need some kind of plastic storage container, a sealant for the lid (if it's not already airtight), and a rod with a maximum diameter of 24 mm (scale up the model if you want to use a larger diameter). My goal was to create a system that doesn't require metal screws or nuts, so you won't have to worry about drilling precise holes for them. I used a double setup because the KIS box is large enough, but you can add as many racks as you need. For one rack, you'll need to print two holders, two holder nuts, and as many feeders and feeder nuts as you have filament spools on the rack. The feeders are M8, so they require an 8mm hole in the box to be installed. The feeding holes are 2.5 mm, providing enough clearance for 1.75 mm filament. If you think there's not enough clearance, drill through with a 3 mm drill. The holders are M24, so they'll need a 24 mm hole in the box to be secured. Make sure to screw them in tight. I designed the holders with a 3 degree downward angle because the walls of the box slope at 93 degrees (check out the photos for reference). Please note that the clips I used are specific to the plastic box I have, so it's unlikely they'll work with other boxes. However, I've included SolidWorks files (.sldprt) in the .rar file for you to modify and remix as needed.
