Tubes4shelves v1.0

I just moved and I need a storage shelf for my cellar that's sturdy but not over 5 feet 7 inches tall. I wanted to build a storage shelf for heavy loads using PVC pipes, thinking three tubes nested inside each other (16, 20, and 25 mm diameters) would make the whole thing rigid enough. Unfortunately, this isn't the case, but it's already good for a first try! One learns from mistakes, so I'm sharing my file and sources in case you can improve on the concept. Since it's free, if you make improvements, everyone wins. The idea was to have a PVC structure that supports wooden trays and simple printed parts, all identical (no symmetry needed), to create a shelf that can hold heavy loads. The wood, tray size (120 x 60 cm), and fact that I built the structure for only two trays must play a role, but I expected better results. It's still holding 154 pounds, which is encouraging for a version 2. The files are designed for 25 mm diameter PVC with 0.5 mm margins and 3x20 mm wood screws. The OpenSCAD files can be edited to fit your dimensions. Use the "test ring" file to test your tubes by adjusting the margin. Then use a tray to build the structure using the positioning tool. The positioning tool is used to mark the plate, which gives you the maximum length of the PVC tubes in both directions and the position of the cleat to place the screws that fix the first rings. Cut the tubes to the right lengths, place two rings at each corner, add tubes with rings about every 40 cm (pay attention to direction), secure the tubes to the rings and support rings along the length using a plank screw object or without it just to mark the location of the screw, correct the length if necessary, and add support crossings. Place them on vertical tubes at the bottom for the first one and then horizontally for the next ones (use an object at each corner if you're solo), each time using the "on" object to fasten the board with the tube, and you're done!
