Level sensor project (3D printed box)

[Wimberleytech]

Here is a project started before I had a 3D printer and had planned to implement using a BUD box or similar.

A friend convinced me to buy a 3D printer and that changed everything (even the way I was providing power).

I found 18650 power bank on ebay for about a dollar.  I harvested the guts out of the power bank, and copied the box design (for mounting the guts) and added space for my board.  Much nicer result than going with an OTS box.
