This is a simple bracket for Mac Valve, model # 35A-AAA-DDBA-1BA, commonly used in turbocharged cars. I made this for my Z32 300zx, but decided to put this out there in case someone else finds it useful. It requires a 2 M3x20mm screws and some m3 nuts, which are inserted into the back of the bracket, to secure the valve to the bracket. The bracket can then be bolted down with 3x M5 bolts.

I printed this in ASA and would suggest similar if being used in your engine bay. I printed the bottom without supports for the nut slots.

There are 2 versions of the top, one with a (Nissan) Z logo and one without.
