Smartphone Camera Rig Basic/ Beastgrip

thingiverse

LENSES: I added-on lenses from Vivitar, and bought a set of 37mm Polaroid lenses similar to those from Beastgrip. The larger Vivitar added less vignetting, but the Polaroid was slightly better quality overall after cropping the circle. UPDATE: Version 2 offers more flexibility. Instead of using a threaded nut to hold the phone holder in place, you can use rubber bands to apply tension, and still add the nut for security. I added more robust right and left grips that feel comfortable. Just sand the edges. I needed a simple, easily printable rig for my Samsung s6 and 8 made with cheap hardware from any hardware store. I love the idea of Beastgrip, and might buy one in the future, but had a few days off for Christmas to challenge myself. Solving the mechanism to hold the phone securely was the most interesting challenge. I considered springs and bands, but decided to use friction. The phone is held in place by squeezing the jaws together and tightening the knurled nut. My prototype was done in natural ABS, using steel 1/4" 20 all thread, with a little personality added with wood and black PLA, and brass 1/4" 20 all thread. The lens holder will hold a 37mm filter ring that the Polaroid lens screws into. It's not really designed for a non-centered lens, but can be modified to fit on. I will attach cold shoe or Picatinny mounts to support a mic and flash. Adding a tripod mount was never considered, but can possibly be done at a later date.
