Summary

This is an HO Train scale sign for an Ice Cream Parlor. It is designed to have 3mm LEDs mounted for lights. The back piece covers the wires.

Instructions

-Print the front and back. It is scaled for HO.
-Install 3MM leds in the 8 holes in the channel provided.
-Wire them up as you desire using the wire channel. Do not allow the wires to stick up beyond the top much or you will not be able to get the back on to cover the wires.. I wired every other one together for two circuits and added a blink circuit to alternately light them.
-Hot glue in the wires
-Attach the back wire cover with hot glue or instant glue.

Install on your HO layout.
