These are plastic, 3D Printed finger screwdrivers for travel. I initially created this to use on the screw for the baseplate of my camera, as you can see in the photos. If I would take a metal allen key with me on the plane, it would get confiscated depending on the country of travel. So, I decided to make these so that if it does get confiscated, I can make a new one cheaply and easily. They are not intended for high force activities, and I've only tested these for a "finger" tight torque.

The handle is 3.5 cm long. The heads protrude 6 mm for the Flathead and Phillips sizes, or 10 mm for the M# sizes.
