Rounded Box

This is just a rounded Box. It is a 1x1x2, so if you scale it to 100 mm H/D, the W will be 200mm. The lid is 1/5 the the H, with a 1/10 H sink.

So I built this at 50mm x 50mm x 100mm. The lid is 15mm thick, with 5mm of that sunk into the box.

The fillet on all of the external edges, as well as the inside is set to 3mm OD (outside diameter), The lip of the box,and lid do not have a fillet. The inset on the lid is -0.5mm offset, that should be enough for a snug fit.

I can edit this file if there is a need later on, feel free to leave a comment if you need something, or suggest a change.
