WORK IN PROGRESS
Requires soldering wires to the main PCB of the indicator, and wrapping the wires in the 3D printed part to contact the battery.
- Rev1 was assembled and working, but is frustrating to assemble.
- Rev2 will add spring flex contact on positive sides, more holes for assembly, haven't tried yet.
Note that some of these digital indicators are slightly different diameters at the top, but, the face diameter should be the same.
PETG only.
Print flat side down with support in some areas.
The scale slows down at 1.3V or so? Eneloops should be ok.
