Z height adjustable bracket for Neje Master 2S laser engraver

Edited the original design so I could use the stock screws to fis the bracket, going from inside the bracket to the back of the original mount, adding a couple of M3 nuts that Ialready had in abundance; and I designed a M3 nut housing in the side knob, also making it larger.
Also added a handle for the fixing screw that you can not print (sorry that I included it in the design, you will have to manually remove it), it is designed for allen key knurled round head.

You will probably need to file thinner the side of the brackets to the laser slides happily up and down. I placed a small piece of rubber between the serrating screw and the laser side, I don't like the idea of scratching the housing with metal on metal contact.
