Airsoft M4 Crane/Sopmod Stock Battery Case

thingiverse

Bolt-on battery box/case for a 3s 2.2Ah battery and sopmod stock. I designed this for a snug fit on a 109x34x27mm battery https://hobbyking.com/en_us/zippy-compact-2200mah-3s-40c-lipo-pack.html Will not fit on my G&G CM16 stock. My reference stock came from a Black Ops Viper which was likely SRC oem-ed. Hopefully this will work for the majority of other stocks. I included an stl titled "main body fitment test" for a small test for both testing fitment to your stock and for breaking in the nuts in case they come out a little tight. Print three "connecting nut 2" and one for the rest. Orientate the nuts flat and the main body straight up with the bolts horizontal. Slide the cap through its slot and thread nuts on the bolts several times before installing. The nuts are supposed to be hand-tightened since there's no metal. Loctite the threads if you're worried about these backing out. This is the first time I've uploaded anything to Thingiverse, so if any critical details are missing, let me know.
