iPhone Tripod Mount - Threaded

I like the design of user todbot's "iPhone Tripod Mount" a lot and I've been using it for a while now! It's flexible enough to yield a bit when inserting the phone, and then keeps a sturdy grip! The design is simple and elegant.

My one gripe is that the hole in the bottom of the mount, which I assumed was for screwing the assembly onto a tripod, has no threading and too much clearance to stably grip onto standard tripod mounting hardware. It's enough to work on a stationary, upright tripod, but the camera mount became undependable and wobbly on moving shots or steep angles.

Enter my remix! The change is minor, but transformative. The hole in the base is narrowed and threaded to fit a 1/4" - 20 UNC thread. I made no changes to the part that grips the phone, but now the mount itself grips onto the tripod snugly and doesn't complain if I angle the camera sharply or move abruptly. Very nice!
