Vertical iPhone 4 Tripod Adapter

I designed this adapter in SolidWorks to connect an iPhone 4 to a mini-tripod. The bottom opening has a 1 inch diameter with a second hole to accommodate the threads. Anything with a similar width to an iPhone 4 should fit, but it was designed specifically for an iPhone 4. I included the SolidWorks files if you would like to customize it. Thanks!
