Would anyone be able to do me a massive favour for a project and take some as accurate as possible measurements with a micro meter ideally of a duncan yoyo cap or of the freq mods cup please. A few reverse of cap photos would also be very welcome ! :wink:

Here’s one of my Hornet caps. I measured the OD of the cap to be 1.994 inches, and the corresponding ID of the cup on the yoyo is 1.991 inches. The height (lying flat) on the outer edge of the cap is 0.119 inches. Sorry, I couldn’t get a weight measurement, but you probably could find that online somewhere. Hope this helps!
