Bat Signal for iPhone

thingiverse

Need rescued? Alone in a desperate place? No cellular reception? Call out with the flashing beacon that's within reach - Print out the reliable Bat Signal and use your mobile device's illuminating flashlight to signal for rescue!! I came up with this notion just last week and couldn't shake it loose. After multiple attempts, I made it suitable for all handsets by refraining from creating a latch attachment; instead, there is an enclosed ring where you can comfortably secure the projector right in front of your flashlight using two fingers. A built-in hole system enables it to be attached safely onto a keychain while you're on the move! It's simple and easy to print out - it only takes about 45 minutes with settings at 0.25mm resolution. Please note that this model is for personal use only; it can't be used for commercial purposes. Instructions: Designed to be printed with no supporting materials. After printing, securely grasp the unit between your two fingers directly in front of your smartphone's light beam to call out for help!
