Turbo pressure tester

I got a boost pressure DTC code on the car P2263, and wanted to test if there is any leak in the turbo pressurized line. This is an air intake cap design housing a valve stem to pressurize the system.

air intake diameter 80mm
valve stem hole 12mm

scad file is attached so you can customize if you need to.
