The Ray Gun is a 3D printed prop and uses hobby electronics to produce lighting and sound effects. These electronics are listed in the Bill of Materials found in the downloads section on the CRAFT page under "RG - Documents". To make your Ray Gun light up and make sound, you have to install these electronic components which requires some minor soldering skills. Later this week, I will be adding a full build video tutorial to the shop showing every part and how it fits together, including the electronics.
Hello Andrew, is the tutorial video coming soon?
