This Volt Meter is not a Bomb

I made this project in about two hours. It is a mini volt meter from Adafruit in a 3D printed case in the shape of a grenade with banana jacks for connecting test leads or probes. It can be used to test batteries or circuits in electronics projects. It can read voltages from 3V to 30V DC.

I printed the two halfs of the grenade on my Makerbot Cupcake CNC. I got the 3d design file from Thingiverse. It’s “Hand Grenade” by Hairygael (Which is a derivative of “Hand Grenade” by MNinventer)
