This is a simple holder for a cell phone. Works with iPhone 6 and larger format phones. Is intended to mounted to the edge of a desk. For added strength, I separated the holder into 2 parts. Print the clamp laying on its side to form a C (with supports for the hole). Print the holder standing on the bottom (no supports). Print both pieces and then cement the clip to the back of the holder. If printing with ABS, simply use acetone to "glue" them together. Hole is intended for 1/4-20 hex bolt bolt to use a clamp lock.
