Universal smartphone tripod mount

pinshape

This is an adjustable cradle designed to attach a smartphone to a standard tripod. The thread required to fit my tripod was a 1/4-20 UNC, which seems to be the standard on most tripods, especially those in the cheaper end of the market. Fortunately, I had the correct-sized nut lying around in the shed, one that 'might come in handy someday'. It should adjust to accommodate most smartphones with ease. The photos show a Nokia Lumia 630, which is quite small, and a Samsung Note 4 in a protective case, which is a bit on the large side but still has some adjustment left. It also fits an iPhone 7, although I'm not sure about the 7 Plus. The V-groove provides clearance for buttons/switches and helps secure the phone in place. It might look a bit chunky, but once clamped in position, you can be confident your phone is securely attached. Printed in ABS with a Flashforge Dreamer, I used the standard ABS settings with an extruder temperature of 220 and platform temperature of 105. No raft or supports were needed; only pre-extrusion was necessary. The main body parts were printed at 15% infill, while the knurled knobs were printed at 100%. The three main parts fit together perfectly without requiring any post-print finishing. I inserted a 1/4-20 UNC nut into the base to attach it to the tripod. The printed threads were a bit tight, but running them with a standard M6 bolt loosened them up quickly. However, the knurled knobs presented a different challenge altogether; they need significant refinement to fit properly. Next time, I'll simplify the design by using 5 or 6mm thread and plain shank for the rest.
