Cheese Grater Ball Cap

Clips/snaps onto the little button cap at the top of a ball cap. Update. Two versions in the print profile.New regular clasp fits 13.9mm, 14.2mm, and 15.5mm diameter top buttons.New larger clasp fits 16.3mm top button.You can use a digital caliper to measure the top button to determine which one you need, or print the test plate and see which one fits. The old snap on version was very specific, 14.2mm diameter with the part under the button 13mm.The old slide on version was less particular. The “New Snap” version from the updated profile is a more universal fit. I've removed the other plates (older versions).
