Airsoft NPAS Quick-Adjuster (TM MWS)

A handy one for GBBR users;
We've all been there - you sit at home fine-tuning your NPAS valve before a game, only to get to the field and your gun's shooting just slightly too hot to pass chrono. No problem, just take your rifle apart, pull the bolt out, take off your gloves, fiddle around with the hex wrench for a solid minute, reassemble your rifle and... it's still too hot. Rinse and repeat.

Let's make things a little smoother. With this tool, simply lock your bolt back, insert into the front of the nozzle, give the dial a half-turn, send your bolt home and breeze through chrono.

I designed this to work with NPAS valves for the Tokyo Marui MWS (specifically the Federal Concepts one), but it should work great with anything that requires a 1.5mm hex wrench to adjust and whose nozzle dimensions match those given in the above diagram.

You will need:
A sacrificial 1.5mm hex wrench
A little superglue

Simply print, assemble by super-gluing the gears to the knob/hex stalk while inserted into the main body, and then dremel the 90° bend off a standard hex wrench (leave at least 38mm length on the wrench, as pictured). Insert this into the stalk with a drop of superglue and you're good to go (you should have around 11.5mm sticking out the end).
The gears should turn out pretty strong with PLA, so hopefully you don't need to worry about chewing them apart.

I'm happy to adapt this to work with other NPAS systems (such as WE/RA-Tech), which would just be a matter of changing the size of the hex stalk. Just drop me a message if required!
