Designed to make a screwdriver out of a 5/64" allen key with a little crafting.
Print both pieces without support. Shorten the short end of the allen key until it fits into the slot on top piece. Enlarge the hole in the bottom piece until the key fits through. Plastic epoxy the two pieces together for a finished screwdriver.
The Inventor files are included if you feel like remixing it for a different size allen key or another creation.
