I meant, I’m not sure if it may damage the yoyo. I tried it again and I now see that it may not actually work after all because of the way the outer silicon wall bumps out a little. I thought that it wasn’t quite fitting because the response pads stuck out but thats not actually the case. Oh well. I can foresee a side effect that would be compatible with a “step” part that contained a silicone groove, enabling you to add width to your yoyo. I could see someone more skilled at modding then I sanding the part to make it fit.
