Portable monitor stand/feet

I bought a MNN brand portable monitor, its advertised dimensions are a 15.6 in monitor with a 3 mm thickness, I found it to actually measure slightly wider, but its a great monitor but the case that came with it wasn't very sturdy so I made some feet, took a few tries to get the proper stability and angle for me, Its set at roughly a 7-10 degree angle,I can't recall but I printed two one for each side and its been perfect for me.
