Airsoft Case for 18650 Batteries (3S 11,1 V - PEQ Box - Picatinny Rail)

This Case houses 3 18650 Batteries and can easely be mounted on a picatinny rail. Its designed to look like a Laser Box or PEQ Box.

The 3 18650 Cells are wired in series, so the Voltage will add up to the same Voltage as a 11.1V Lipo. You wont need to solder anything except your Main Connector (to connect the Battery Pack to your Airsoft Gun). The Batteries are held in place by M3 Screws from both Sides and the Batteries are Connected by wires, that are screwed onto the M3 Screws with Nuts (as seen in the Pictures).

There are two different versions of this case, one has no visible wires (they are routed through the Picatinny Rail) and the other Version has holes for cables on the back.

When measuring the Screws I measured them with the Head (not only Thread lenght, but overall lenght of the Screw). Most Screws dont need to be the perfect lenght, you can use longer/shorter Screws on most parts. For this Project you will need the following Screws:
4M3 with 30mm lenght
3M3 with 15mm length
5M3 with 10mm lenght
9M3 Nuts
2*M3 Washer

More specific instructions will follow, but the Case itself is definitly ready to print and the build more or less self explaining. Dont forget to check out my other Desings ;-)
