Joint for 14" Wire Cubes

This joint works well for the larger diameter wire shelves (14" on a side) used for Guinea Pig cages. I first tried https://www.thingiverse.com/thing:4927095 and it was too small. So I took the existing joints that we had already purchased and using calipers, I re-created it in OpenSCAD. I enlarged the wall thickness quite a bit to make it stronger. I also chose not to model all of the joint spaces to make it easier to print. I printed this in black ABS on a Bambu P1S and they are holding our Guinea Pig enclosure together.
