Case for multimeter.
Max multimeter dimension is 180x100x60mm.
Space for wires, probe, temp sensor, fuses...

Cases: print with minimum supports (only on latch area)

Latch: slide in place on top shell when open. (maybe will need some sanding to slide smoothly. I choose to do it with tight tolerances to have a firm movement without any sloopy feeling. If you is not much into sanding, you should print it at 101 or 102% size)

Pin hinge: they are split in a half for better printability and strenght. You need four of these. Maybe you will need to clean case holes with a 5mm drill before mounting.

Seal: to be printed in TPU 30% infill. [optional]

Handle is optional to be screwed, if you want
