We all need help sometimes and if you’re a fan of most things geeky you know exactly what signal to flash in the sky to get the help you need. The Batsignal. So what if you don’t have access to a flood light, if you have a cell phone you can have your very own signal with the Mini Batsignal, the Batsignal for your cell phone.
This is a small plastic signal made specially to fit over your phone’s flash. If you’re lost in a crowd and need to alert your friends to your location, flash this on the wall, your buddies will know exactly where you are.
It is 3D printed and designed to be held with two fingers while you operate your phone. It’s small, and potentially pretty useful if you’re ever lost or need help because honestly, just about anyone is going to follow a real life Batsignal. If you happen to have your own 3D printer, the designers have made the plans free so you can print your own at home. The Mini Batsignal is $5.85.
