Galaxy S4 Tripod Mount (Remix)

You'll be surprised (or at least I was) the first time you use your phone on a tripod. It's super easy to frame and focus, and the pictures come out much better than handheld. You can use a "regular" tripod, or there's a wealth of tiny ones (e.g., here , here, here, etc.) that fit on a table top; great for shooting small parts, documenting research or the steps in a project, etc. (see here, BTW, for a good tutorial on how to photograph small objects and projects.)
My printer apparently has some issues printing small threads, so I took another crack at Giufini's fantastic Galaxy S4 Tripod Mount. This one uses a 1/4-20 T-nut (e.g. here ) to provide the mate to the tripod mounting screw, providing a strong and long-lasting attachment. If you don't have one of these T-nuts in your garage parts bin, they're readily available in any hardware store.
The flats on the mount also let it work as a free-standing horizontal or vertical tabletop phone holder in a pinch.
