Battery charge indicator

thingiverse

For any rectangular battery, print to the dimensions of the battery and slide over to signify charged and used batteries. Align the notches with the contacts/wire of the battery, most are not central or are on one side, so remember that to keep track. Min recommended width: 24mm, to keep the graphics. Any smaller should be resized when slicing 30mm = 15mm at 50% scale etc.
