The triple finger buddy ring is designed to support the MCP joints across the index, middle, and ring finger to encourage stability in the joints when applying force such as twisting a lid. The middle finger remains unenclosed in order to allow minimal limitation while wearing the splint, but still allows for support where needed.

This ring was modeled around roughly a size 9 base, and one side is slightly larger than the other to accommodate natural deviance in finger sizes.

I would recommend starting with a slight scale in the X axis for adjusting the actual ring holes size. If the holes are spaced too far apart for your hand, scaling only in the Y should allow minor adjustments to accommodate this.

Please share if you found this helpful and what settings you changed and what size rings you typically wear (if known)!
