Dry Box System

myminifactory

This is a custom dry box filament feeding system I've designed from scratch. To make it work, you'll need a plastic storage container, a sealant for the lid (unless it's already airtight), and a rod with a diameter of up to 24 mm (scale up the design if needed). The goal was to avoid using metal screws and nuts, which means no precise drilling is required. I've used a double setup because the KIS box is spacious enough, but you can add as many racks as you like. For one rack, you'll need two holders, two holder nuts, and as many feeders and feeder nuts as there are filament spools on the rack. The feeders are M8, so they require an 8mm hole in the box to fit snugly inside. A 2.5 mm feeding hole provides ample clearance for 1.75 mm filament. If you're unsure about clearance, use a 3 mm drill to enlarge it. The holders are M24, necessitating a 24 mm hole in the box to secure them firmly. The clips are specifically designed for the plastic box I used, so if your container isn't identical, this system might not work for you. The .rar file includes SolidWorks files (.sldprt) for modification and remixes. To print the components, use PETG or PLA (only indoors, away from direct light): - Feeders and feeder nuts: 0.15 mm layer height, 30% infill - Holders and holder nuts: 0.2 mm layer height, 20% infill - Clips: 0.3 mm layer height, 100% infill Print all the nuts without support. Print the holder and feeder with their axis vertical (perpendicular to the table). The holder requires support only where it's holding something in place, not where the screw is located.
