I wanted a tool to be able to let out/release gas from my WE Tech gas blowback magazines that I could control more easily and be able to use with gloves on. This was the quick idea had. I reused and remixed the flange (or mag well) part from a BB speed loader I found online.
I used a small spring that I cut to length. It is hard to install so please, someone, feel free to remix for easier spring install. You can also use this without the spring if you wanted. The spring just keeps the trigger from hitting the mag when inserting it into the tool. I ended up crazy glueing the spring to the trigger and quick setting it before I installed the trigger into the flange.
Print settings I used:
For flange:
PLA, 0.2 layer height, 20% infill, 2 parameters, use organic supports everywhere, print mag well down.
For trigger
PLA, 0.2 layer height, 100% infill, 4 parameters, use organic supports on plate only, print on the side.
I used an m5x20 socket head screw and hex nut and a m6 (or an m5) spring cut to about 5mm.
*I included the STEP files for easier remixing using popular CAD software.
