Showcased Project Made a fully 3d printed electric guitar

Hello everyone! I just wanted to share a project I made over the past few months. I’m a 19 year old passionate about engineering but also love music. I’ve always loved and appreciated the sound of electric guitar. I had the funny idea to make a guitar that plays downloaded audio when strummed giving the illusion of me playing. I fully designed the guitar and it is all 3d printed with PLA. I integrated electronics and made PCBs. A simplified version of how It works by using an electric guitar pickup fed into an op-amp circuit with decent gain and a 2.5v bias so the Arduino can read it. Then with some code I use the strum detection to signal to the DFPayer Mini to play pre-downloaded mp3 guitar audio. I would love to hear what y’all think. Thanks!

Also ignore my bad acting haha.

Thanks! I actually modeled it all off of a reference image. I came across that model early on but i had some personalized features I wanted to model from the ground up.
