M41A Rifle magazine foot for Arduino implementation

This model is an addition to the sound project of the 3D printed M41A rifle from the movie Aliens.

Electronics are placed in place of the magazine and control elements such as a switch, wheels for adjusting the volume and a door for a 9V battery are located in the base of the magazine.
