These are STL files used to create the 3D printed Minnesota Vikings Neon LED sign. Other materials used to build are listed below. I print in multiple pieces and use a soldering iron to weld the pieces together and 22-24 AWG wire and solder to connect the light strips to each other.

Neon LED strips: There are several brands available. Some are cuttable every 1 cm (Lamomo brand), others are cuttable every 2.5 cm (Meijiajia brand). I've linked the 2 types below. I built this one using the Meijiajia brand lights.
