Just started my physical CAD for the casing!

I started cadding the casing for my hall effect current sensor! The hardest thing about it was making sure the battery could fit while fitting the mounting screws. It was a pretty close fit but the screws shouldn’t need to bear much load so hopefully they don’t break the 3d print. I spent around 20 minutes trying to fit the screw holes in a way that looked okay and shouldn’t intersect with anything on the PCB.

Then I realized that I wanted the top part to interlock with the bottom, so I added a small slot around and thickened the walls so the slot could fit. I also had to make sure to leave space for the hall effect sensing circuit could come out.

I’m trying to keep this as small as possible that way this can be some kind of handheld device.

Next time, I’ll continue to work on the top part of the container and polish it up.
