Simple Magnetic Sliding Catch Box

A simple container using a sliding magnetic catch, slide one way to lock, the other to open. This version is designed for 5x5x1mm rectangular magnets, though 5 dia x 1mm disc magnets could be used. I used https://www.first4magnets.com/product/5-x-5-x-1mm-thick-45h-neodymium-magnet-04kg-pull-18915 It assembles using dovetail joints, and should require limited (or no) finishing. The magnets should be installed with alternating polarities (this is fairly easy, as they will stick this way round edge to edge)..
