Adjustable Z-endstop support

I forgot BOM... (Thanks @ElevatedisScout)

1 x 4x40 mm Phillips Rounded Head Screw
1 x 4x10 mm Socket Head Screw
1 x 4 mm T-nut
2 x 4 mm hex nut
1 x spring from the heated bed (I used a yellow one)
the 2 screws for the sensor board are the original ones





I like JELaVallee project, hope this is a little improvement
I made some mods also not to use Brass Embedment Nut.
By the way, the upper part looks impossible to get in place without sliding from one end of the frame, do not disassembly the frame!
I tried to make it as tight as possible so just put the "hook" in place then force a little bit toward the rear part of the printer it should jump in.
