I came up with this 3D printed design for quickly checking the voltages of my 18650 cells:
I doesn't do anything that you can't do with a standard volt meter, but it's much quicker and less fiddly than using the meter probes and can be used one handed.
And its powered by an 18650.
It uses a standard Chinesium panel voltage meter ( 26 x 46mm not including bezel ), rocker switch to turn it on/off and a single slot 18650 cell holder, which just clips into the back, plus some wire, solder tags and screws (M3).
The .stl files are attached in anyone wants to print their own.
