Tricklock puzzle

A simple tricklock/puzzlebox. It needs to be assembled, this is not a print-in-place puzzle, so whoever prints/assembles this box will know how to solve it.

The goal is to open the box by pulling on the handle. In the current design, it's possible to open the box right from the start with a lot of force, so tell anyone who wants to solve it not to force it open. The key is semi-optional, but a useful tool.
