The file 'Rapid Prototyping Frame 3D Printer Model' is (step,stl) file type, size is 435.5KB.
These are pieces I like to use to quickly make a shapes from cheap 16 mm PVC tubing. They friction fit, but you can glue them too.
They are designed such that all the tubes intersect through a single point.
If you do not like the angles or diameter size, go to onshape and change the parameters. If you need more acute angles than 90 degrees, also increase the insertion length parameter of the model. You can also change the diameter parameter, I added 0.2 mm for play.
I uploaded a series of most useful angles. Keep in mind you might need to mirror parts in your slicer to get all the possible parts to make a cube.
