This is an extended battery door for my sons new airsoft rifle. This is specifically for the Matrix "Calico Jack" Polymer M4 Airsoft AEG Rifle w/ M-LOK Handguard & MOSFET (Model: PDW / Tanker Stock / Tan). AKA Double Eagle M904. I got it for him on EVIKE.com = ID: 20710 (AEG-MTX-M904N-E1-TAN)

The original battery door was very short and the battery cables were hard to manage inside the stock cavity. So this part allows the battery to fit into this cover and only the cables need to fit inside the stock cavity location. This helps with the time required for battery change over as well. This prints well with Organic Supports in the orientation supplied (see images)

Included are three lengths. The stock length (30mm from flange, one that extends to the second stock notch detent 78mm, and one that fits inside the stock on the third notch 125mm.

I have supplied the files in STEP, 3MF, and STL. Also included is the link to the Onshape file.
