Description
I designed and made this to monitor the battery voltage on my travel trailer. The main hole is slightly larger than 1-1/8" (actual size 1.135"). To reduce battery load, I added a momentary contact switch with a hole slightly larger than 7/16" (actual size 0.47").
I used black PLA with 20% infill.
