Parameterized box with magnetic lid

I was very surprised not to find something like this, so here it is! Properties of this box:Fully parameterized (Fusion 3D) in a way that the available volume inside the box is the “primary” thing that is specified/preserved. I find this very useful to then make “inserts” for the box - those become very easy now that the inside dimensions of the box are specified, and the inside of the box is rectangular (intentionally no fillets for the inside corners).The lid clearance is specifiable for a good fit on your printer (after a couple of tests!)The lid stays closed with a magnet on the center of each side. This lets you be slightly less precise with the fit of the lid, because it doesn't need to say closed with the friction of a perfect fitThe magnets are in the sides, which again lets the rectangular prism of space on the inside of the box stay uninterrupted.
