Rubber Band Guitar

This is how the guitar looks right now, still in the process of making some modifications to make it even better. But overall, it sounds great and looks fantastic too. You can check out this video to see for yourself: https://www.youtube.com/watch?v=6a567h_lyL8. Printed at a 0.2 layer height, the guitar cover measures approximately 180mm in length, plus an additional 180mm for the handle, and about 76mm for the end piece. The total size is 406mm long and 262mm wide. It took me around 11 hours to make the guitar cover and roughly 4 hours for the lid. The other pieces combined took around 4-5 hours, so in total it's been around 19-20 hours - almost a full day of work. You can use any type of rubber you like. I happened to have some rubber from old bracelets lying around, so that's what I used. As for the plug at the end, you can either 3D print one or use a cotton swab instead. Just insert the rubber into the cut end of the cotton swab and press fit it in place.
