AAA Battery Conversion to Caliper

I made this AAA Battery conversion to the caliper a different way, so you can still holder the Caliper in your hand, plus you can lay on the table and it support itself up, for easy reach again.
When assemble, remove old battery cover as not needed.
Also make sure to clip the cover on the bottom rounded part of the Caliper, then hold in place with the screw on the Caliper.

Increase opening for the button area, so you can turn on/off easier.
