It is a Cell Phone Forearm holder that I will be using for Halloween. It will hold a Motorola Droid Turbo without a case. I created CR2032 battery holders so you can wire up some led lights. Printed using PLA but you can choose your preferred filament
You may have to do a little heat forming on the plastic and mold it to your arm. I recommend using a heat gun, while it is NOT on your arm, until it is pliable. then move it to your arm, with a long sleeve shirt on or some other protecing material, so you can mold it to your arm
