My dad gave me a toolbox for my car. I guess it must have been about 35 years ago. It's just a toolbox but my dad passed away in 2010 so my toolbox has sentimental value. The hinge, which was just a piece of plastic that joined the top and the bottom of the case eventually tore, so I printed these hinges and fitted them to the toolbox with rivets. Not rocket science, but hopefully my toolbox will be with me a little longer :-)
