This is an adjustable mount that attaches your smartphone onto a tripod. The design has been minimized for fast printing. Just print two of these, grab a nut and some and bolts and you're in business. The hardware used is all 1/4" x 20, so in addition to the print, you'll need: - 1x 1/4" x 20 hex nut - 1x 1/4" x 20 wingnut or [jig knob](http://www.rockler.com/5-star-jig-knobs-through-hole-insert) - 1x 1/4" x 20 hex-head bolt. This should be at least **0.75"** longer than the width of your phone.
