Hey, I just modeled this on Fusion 360, and I am super happy to share my work with the masses, I just made this which is a sturdy 3D case for CMF earbuds 1. One only needs to attach a simple elastic through the hollow hole, in a loop, and it can secure your earbuds, it prevents scratches, damage and one can also customize one's name on it, up front or anywhere and can emboss it on fusion, if needing any help with the customization part please do reach out to me will be most happy to help.
