Description
Recreation of the commercially-available wire straighteners.
Simple print-in-place hinge with no supports required.
Can be printed quickly whenever its needed.
Close the roller around the wire with your hands.
Grip it tight and forcefully pull the wire out of the straightener, through all the bumps.
The small bumps will bend the wire in all directions and straighten it out.
Repeat with more passes if needed.
Plastic is softer than metal wires, so the wire straightener will likely get scratched. But just print another one if needed.
