Frame to mount a mirror on Tronxy X1

I needed a better way to attach the printing bed to the acrylic moving Y axes. The bulldog clips where unreliable and took from the usable printing area. The PCB that came with the printer was dented and almost unsable. It was a nightmare to level the bed, therefore I mounted a mirror that attaches to the undercarriage by this minimalistic frame.
The frame is glued to the back of the mirror.
This is just one of the mods for the Tronxy X1.
