Filament shelf supports for storing filament spools, filament spool boxes, etc on a wall. Designed to be used with standard 0.5" EMT conduit.
Inspired by RepRack https://www.printables.com/model/129024-reprack-system-by-repkord but design to use less than half the filament and fit 2 brackets on a Prusa Mk3S bed for easier printing.
Buy enough EMT (Electrical Metallic Tube) to span the desired distance twice (10' and 5' lengths typically available. EMT can be cut simply and cleanly by hand with a tubing cutter and possibly some pliers to torque the). Remove any stickers with a heat gun and clean the surface with mineral spirits.
Brackets were printed with PolyMaker PolyLite PLA Pro for the strength and printing ease of PLA with increased toughness.
Design is optimized for Arachne slicer default in PrusaSlicer 2.5.0 allowing for strong perimeter-only prints (# perimeters set to 20). Filament temperature increased to 220C for higher flow rate and PLA Pro specs. Speeds were increased to reduce print time without a noticeable decrease in quality with draft mode 0.30mm layers.
