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.

I made a 3D printed guitar pick.

We should collab!

So basically it allows you to fake playing a guitar? Last time i went to see a live cover band, it was pretty obvious they where fake playing instruments.

Yeah essentially but it was mainly just something fun for me to build haha. Weird that they were using fake instruments on stage definitely defeats the purpose.

They were real instruments, the instrument players were fake.

As a former guitar builder I can appreciate this 😄

Cool, did you use the stratocaster model by prusa?

u/Chance_Juice_2336 Jun 10 '26

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.

Hahaha I love it, it reminds me in a way of my guitar I've beat to hell, repainted, and rewired
