You have 2 broken tables with 2 missing legs?
Don't throw them away, it may be possible to repair them with a rope and get a slightly higher presentation table for your 3D models as a result ;-)

Inspired by the Impossible Table I developed this impossible repair of two tables with missing legs which look quite normal from the far distance - and cause confusion when you come closer.

I added the FreeCAD file and also recreated this in OpenSCAD to allow you to adapt it to your needs.

You have never customized a thing?
Don't worry, I optimized this thing for easy customization.
Just follow the instructions in the last picture, install OpenSCAD (only 50MB) and customize it with a few clicks there

Notes: 
It is important that the legs don't bend too much. Use more wall layers than normal e.g. 5 layers.
For assembly thin enamelled copper wire works best, sewing thread is also OK, fishing line makes it more difficult to assemble.
