I 3D printed a docking station for the guns that also enables 5V charging. I mounted it inside a custom sized box that also houses the base stations inside the lid. 8 guns per box. Also, the base stations now mount directly to the walls at my church. They used to be mounted at the end of telescoping marshmallow sticks that attached to the 5V wall charger. The purpose for this change was to get the bases above your head so you couldn't stand in front of it and block it from other players.
