Case for Inexpensive 3.3V Logic Probe

thingiverse

I needed a logic probe that functioned on 3.3V logic levels. These units are unexpectedly difficult to find, but I stumbled upon one from China at an astonishingly low cost of under $3. Despite its affordability, it was essentially just a compact circuit board with exposed wiring. The device desperately required some sort of protective case, and 3-D Printing proved to be the perfect solution. Hopefully, this discovery will benefit someone else's project.
