Dry Box Rod Holders
thingiverse
These two files comprise the top and bottom parts to hold a PVC rod or axle to secure standard filament spools inside a 20-quart Hefty Protect box. They are designed to accommodate a 1.5-inch PVC pipe (smaller sizes may also work) widely available at most hardware stores. The files have an 87-degree offset for the side slope of the box, ensuring the rod sits flat between them. A notch at the top (facing upwards) aids alignment, as the holes are not perfectly symmetrical. This notch also helps ensure the angles line up correctly. M3x20 screws and M3 nuts are recommended; longer screws can be used if desired. Locking nuts provide optimal results. Printing with 15-20% infill is likely sufficient, but these parts were printed solidly without needing supports. Two of each top and bottom part are required, one for each side of the box. They should be centered on the box's sides, spaced 4.5 inches apart from the outside part to the box's bottom. This allows room for desiccant at the bottom and prevents spools from touching the sides. Four standard-sized spools can fit in the box, but testing with your specific spools is necessary to ensure they fit comfortably.
