Camera mount bracket for Piper Cherokee tie-down ring

Piper Cherokee aircraft have a circular tie-down ring on the underside of both wings for anchoring the plane when parked. I designed this mounting plate to be used in pairs and sandwich around the tie-down hook so that an action camera mount (like a GoPro, Virb, Contour, Drift, etc) can be attached onto it.

This is designed to fit a Piper tie-down ring that has the following dimensions: outer diameter is 2 inches across, inner diameter hole is 1 inch across, and thickness of ¼ inch.
