Arduino/Nano Piano Project

Arduino/Nano Piano Project I would like to create a professional looking instructable for a “paper piano” using capacitive touch sensors. There are many of these on the internet but I need someone to help me create one that looks good and works well. I have a 3D printer with conductive “eel” filament so I can print out the parts I require. I have resistors, LEDs (if we want to incorporate these), a Nano, conductive paint. I would like the following: 1. A template to print the trace (the piano part and the required connections); these need to look good. 2. 3D files (in stl format that I can print out to connect components) 3. I want this to be without wires, just printed parts and components and easy to do 4. Fritz files would be also good to show how to complete 5. I have seen instructables for both 15 key and 10 key pianos. I am open to either as long as it integrates with a nano Do not ask me what to do, I am asking you please.
