This add-in is intended to create models of 3D channel letters with a translucent acrylic front face. Channel bodies are to be 3D printed. Manufactured glyphs can be illuminated with different types of LEDs from inside. 

The front face can be also 3D printed or cut with a laser cutter or router. Users can interactively change the model parameters. The generated model can be modified in Autodesk® Fusion 360™ or directly exported for 3D printing.
