This is a remix of jimit5's caliper lipo battery mod.

The changes made are:

• USBC board, changed from micro USB
• All wires self contained, hole for wiring removed.
• Screws and threaded inserts changed to M2
• ON/OFF labeling removed for cosmetic reasons

I found I was able to drill a small hole from the back of the calipers into the main housing, and keep all the wires self contained unlike the previous design.
Otherwise the design remains the same, I just used a different battery and screw size.

Parts:
-1x USBC lipo charging board
-1x 3.7v lipo battery
-1x 1kohm
-1x 680ohm
-1x micro switch
-2x M2x8 screws
-2x M2x3 threaded inserts

Thanks for the design, jimit5!
