I decided to make this thing compatible with all mobile phones by not designing a phone-latch, instead It has a ring where you can comfortably hold the projector in font of your phone's flash with two fingers.It has two holes so you can attach it to a keychain for lovin' on the go ;)This is an easy print, it takes about 45 minutes to print at 0.25mm.If you like my designs follow me :) I make new stuff every couple of weeks.
