Vacuum hose port gate

Tired of plugging my vacuum hose (a Karcher WD one) into the different proxxon tools I was using almost at the same time, I designed this very simple valve, made of 4 parts, plus a 4x40mm steel rod.

You'll need a vice to force the rod into the valve body. The selector must be glued to the rod.
The main part can be printed with 0.3mm layers (the other parts are printed using 0.2mm)
