This automatic fist bump machine has you covered. Even when you are underappreciated at work, this little cute machine will be there for you.

Desktop Fist Bumper
The 3D printed fist is moved by a servo attached to a rack and pinion mechanism. An ultrasonic range finder detects when you place your hand near the machine, and the rest is history. A fun project for Arduino fans.
