What do you mean by this? I’m not quite sure I understand. If you give more info I might be able to help but @MarkD or many other people can probably give better info than I can.
on the 19mm silicone pad groove part of the yoyo (mold actually) do i need a precise tolerance, or can i get away with general tolerance? because i’m not even sure if my design would fil the pad nicely
Which pads are you planning to use, and what are the diameters and depth of the face groove?
plan to use standard 19mm pads, with ±1mm thickness, my groove depth is 1.1mm, in the drawing i put ID 14,003mm and OD 19,103mm

In theory all the yo-yo should be a tight tolerance although I believe most Chinese factories use a tolerance of .0006” for the general yoyo and .0004” for the bearing seat. Those dimensions for OD and ID look mostly fine I personally use an OD if 19.2mm and an ID of 14mm. I think the response pad depth might be a little shallow. I usually go 1.2-1.3mm.
