I needed a small tool box for works around house. Having a proper big tool box (bag) and a lot of stuff in garage, I wanted something smaller one just for each individual project, when only few types of screws, drill bits, screwdrivers, etc are needed and I don't want to take a box with me or full set of screws, bits.
The size of this box is 200x110 mm, upper part can be turned over and therefore closing the internal better and protecting from dust (little more).
I used M3 8 mm screws to fix the handle, but any screw can be used after a little drilling.
Both lids have a little clicking mechanism, but don't expect too much from them, as they are quite thin (1 mm).
Of note, this box is not to be used for heavy thing or throwing as the walls are not strong enough for such impact. I wanted to keep it cheap and quickly printable.

No supports at all.
All parts, except lids, I have printed in extra fast mode with 0.28 quality. It takes: 6 hours for box, 4h30 for upper part, 1h30 for handle and 1h10 for two lids (0.16 quality). Handle can be printed standing upside down or lied on a side (how I printed). Print lids upside down to have a nice print for click mechanism. I designed M3 threats for both a wall of box and handle, so M3 screws of 8-10 mm length should be fine or you can drill through and use other screw with washers and nuts.
