Toolbox Hinge Generator

Inspired by Laura Kampf, this app allows you to design a hinge that allows the lid of a box to swing open and land on top, proudly displaying its contents. The mechanism is based on a four bar linkage.

Once you have a hinge that you like, 3D print a model to test its motion, or generate a 1:1 template PDF to help manufacture it!
