This is a shim designed to help reinforce the 28+ year old hinge plastics found on PowerBook 1400 laptops.

When the PB1400 was first released the plastic that makes up the hinge mounts for the display was more then capable of handling the stresses of being opened and closed. But over time as the plastic has aged.

Originally designed by AEChadwick on the 68kMLA forums I've posted it here with my settings for easy printing by anyone that wants them.
