M249 Foldable Charging Handle Airsoft

thingiverse

The original charging handle was not great for storage. so I designed a foldble one. I made 2 version, both versions need some form of axle the 2,5mmHex verion uses a 2.5mm hex key as axle. (only thing i had laying around) the 3mmAxle version uses a 3mm axle. i've printed and teste it on my Specna Arms M249, and works great. I used 0.16 20% infill, don't know how long that's going to hold, so might print it at 99 or 100% infill when this one breaks. any commentary is welcome
