PVC Tube Bracket

thingiverse

This bracket holds up a 1.5" PVC tube. I designed it for my own drybox. It's very strong, so you can fill your drybox with 2kg spools without fear! ### Features - Most plastic bins have a draft (the walls are "tilted" outward), so the mounting face has a 3.25° offset to compensate. - Designed for bolt/nut fasteners, with room for oversized washers. This way, the mounting force is distributed over as much area as possible on the (flimsy) plastic bin. - Extended walls make it easy to lift up the pipe to access spools, but the pipe will never "hop" out of the bracket. - Takes up minimum possible horizontal space, in case bracket has to fit in a "groove" in the bin's walls. - Fully customizable FreeCAD model included (and STEP format too!) ### Notes - My particular PVC tube had an OD of 1.65", so that's what the model is optimized for. However, between the bowl and slanted side walls, the design can accommodate both slightly larger and much smaller pipes. - The walls are really thick! I probably could have gotten away with thinner features without making it too weak. ### Required Hardware (complete drybox) - 2x PVC tube bracket - 1x plastic bin - 1x ~1.5" tube, cut to length - 4x 5/16" x 1" bolt (longer is okay, but will stick out of box) - 4x 5/16" nut (nylock recommended) - 8x 5/16" washer (max OD = 1.25") You also need a way to get the filament out of the drybox—I recommend an M12 cable gland & long PTFE tube. Also silica gel and a humidity sensor, but that's all out of scope :) ### Instructions Print two brackets. Hold up one bracket where you want to mount it, and mark both holes on the bin. Drill both holes with a 5/16" bit. Repeat on other side (make sure they are aligned!). Fasten one bracket to each side with washers on both sides.
