Pressure release plate for Epax, Peopoly Phenom resin printers (others as well)

This is a spring load pressure plate for the build plate in these devices. Two stiff plates capture 4 stiff springs. Pressure is controlled by screwing down OEM screw. This was inspired by my second build on the Epax X133 which appeared to break the LCD. Turns out it was just a screen protector, probably left on by mistake. However, I continue to use this as it basically puts a ceiling on how much pressure can be exerted by the build plate on the LCD. Many models seem to use the same build plate set up as Epax, including phenom and photon. Dimensions may differ however. Also, the Epax has a slight curve to the top of the build plate, which I matched. This curve may not exist on all machines, though as long as the curve is less it should not really matter. I used four springs from an old CR10 (like this https://www.aliexpress.com/item/32976808769.html, many sellers exist). Holes for M4 screws are including to keep everything aligned and together. I just use two as all the springs are captured.
