Parametric finger ring with e-ticket container

thingiverse

I'd love to wear my e-ticket as a finger ring, but I couldn't find the right size on sale, so I designed this container to turn a bracelet into a ring - not that the bracelet is cheaper. Obviously, you could adapt this design to hold any similar chip. I started with a three-piece compound design, but ultimately preferred a single, monolithic piece (though it took several attempts to get the inner dimensions just right). The minimalist style without a smooth transition between the container and ring was an accident, but it seems to work (and it renders faster too). Be aware that the first compound design has extra space below the container, so you'll probably want a smaller ring diameter than what the tester ring suggests. I'm not sure if STL files will be of much use, but here they are - you'll likely need to regenerate them for your own ring size (and inscription and possibly chip size). To be honest, I don't like how scripts are written right now, and it would be great to rewrite them in a more systematic way. Still, they do what I need. Note that the "mono" script doesn't refer to the standard script - all definitions are inside - but it does use the "bezel" script to calculate side wall inclination. Update 7/23: I've added an asymmetric design. Update 7/28: Even more asymmetric and slower to render is this latest design, which took me several attempts to get just right.
