Update: used some leftover pieces I had left over from a messed up front panel and made myself a custom grip wrapped in the stingray leather.

Works really well together and is a very tight fit. The grip molding and wrap covering took longer than doing the whole camera body lol. The screw is held in by a counter sunk washer within the plastic, and the screw also retains another smaller washer with split spring ring to prevent it from working loose over time.
