This is my guitar tuning stand, it features a bottom holding tray for pegs, screws etc. I designed this using Tinkercad. I printed the test model in Ender Black PLA with 15% infill. I suggest using felt or neoprene to pad the saddle area. You can find 1/8 inch adhesive neoprene pads on Amazon. If your interested I'll post a link

I guess if you wanted to print a TPU based pad as well. I don't know how TPU would reacts with guitar finishes. I have a second version of this I'm currently developing.
