I had bt2 battery checkers but I kept losing them…they were small and let's say I was not the most careful with them!
I got inspired from this model: https://www.printables.com/model/13930-1s-battery-voltage-checker-ph20 by @LCruz3D 
Decided to design a new one with a ring and a different screen holder. Hope it can help you too not losing them.

Print:

  • PLA 12% infill
  • No support
  • Just assemble

How to assemble:

  • Get a 0.28 LED screen voltmeter and solder to the BT2 connector
  • I suggest to put in place the BT2 with the wires soldered through the BT2 hole (it is quite tight fit so it doesn't move)
  • then solder the voltmeter screen
  • Insert the screen in the top part…
  • then press it on the bottom and voila!

Note: the fit is quite tight, you shouldn't have to add glue…but you never know how it will print on your machine ;-0
