Tubes4shelves v1.0

3D model description

I just moved and I need storage shelf for my cellar, but sturdy and less than 1m70 in height.
I wanted to make a storage shelf for heavy loads, based on PVC pipe, thinking that 3 pvc tubes in each other (diameters 16, 20 and 25) would make the whole rigid enough. Unfortunately this is not the case but it is already good for a first try! ;) One learns from his mistakes but also from the mistakes of others so learn from mine, that's why I share the file and the sources. As it is free, if you improve the concept everyone is winning.

The concept followed was to have a structure in pvc (IRL tubes of electricity) that supports the wooden trays, simple printed parts and all identical (without symmetries to check / respect), to have a shelf that can support heavy loads.
The wood (here the agglo), the size of the tray (120 * 60cm) and the fact of having made a structure only for 2 tray must play, but I expected better, waiting to find a solution to rigidify that. It is still 70 kg, it is encouraging for a v2.
The files are intended for pvc of 25mm in diameter, with 0,5 margin and wood screws of 3x20mm.

The openscad files can be edited to fit your dimensions.
Use the "test ring" file to test your tubes by playing on 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 the max length of the pvc tubes in length and width, as well as the position of the cleat to place the screws that fix the first rings.
The tubes are cut to the right lengths,
place the 2 rings required at each corner,
place the tubes with rings about every 40 to centimeters (attention to the direction),
the tubes are fixed to the rings , as well as the support rings in the lengths with the plank screw object or without using it only to mark the location of the screw,
the length is corrected if necessary and the support crossings are placed and screwed,
they are placed on the vertical tubes, at the bottom for the first and then horizontally for the next ones (using an object at each corner if one is alone),
each time the object "on" "which makes it possible to fasten the board with the tube,
and voila!
