Ring Sizer at Home

thingiverse

ScribbleJ is getting married! As I've never been one to wear jewelry, I have no idea what my ring size might be. You can measure it with a string or something, but that's a horrible method since rings are far more rigid and regular... You can go to a jeweler, but since I fully intend to buy the rings online from e.g. Amazon, bothering some salesperson for a sizing seems dishonest -- and of course dealing with salespeople is it's own special hell. So I thought I'd whip up a quick OpenSCAD script to print simple rings in a few sizes, you can try them on and find out what fits right. Not a WIP - but I'll post photos after I've printed some. Instructions Load up the .scad file in OpenSCAD. It's well-documented, but here's a copy of the parametric settings so you can see what's involved without downloading it: // set ring_w to width of ring. ring_w = 8; // ring_thick = radius of ring ring_thick = 2; // num_rings = how many rings to print num_rings = 5; // print_sizes = array of the ring sizes you want printed print_sizes = [6, 6.5, 7, 7.5, 8]; // Spacing of rings rings_per_row = 3; ring_space = 25;
