Welding Square Magnetic

I needed a some welding squares to tack a project together before I really weld it.
Going to town was not an option so I designed this.
These are printed in PTEG so would obviously not stand up to a lot of heat from welding but if your are careful you can get your welding project started. They are what they are so use them or not. It's an example of what you can do in a pinch if you have to.
I have included the FreeCad file so you can adjust the size of square or what magnets you have available. You need to print two pieces and glue the magnets in before tightening up the bolts so they do not get pulled out by the magnetic force of whatever object your attaching them to.
Could even be used for shelving brackets on a metal surface.
