caliper battery storage

thingiverse

These budget-friendly Chinese electronic calipers are notorious energy guzzlers. They also fail to shut off completely when you press the OFF button, except for the display screen. Since the display screen consumes virtually no power, a staggering 99.9% of battery life is squandered while the device sits idle on a shelf. Instead of lasting several years, the battery drains quickly and expires in a short period. Occasionally, I go months without using this caliper, and it's frustrating to discover weak or dead batteries every time. I sought an easy way to disconnect the battery, but no such feature was available. Removing the battery is one option, but where do you store it securely? This tiny clip provides a convenient place to stash the battery safely. The clip should fit snugly around the battery so it can't accidentally come loose. It may need to be enlarged or reduced by about 1% to achieve a perfect fit. To create the clip, use 3 grams of ABS material at 0.3mm thickness with a Z-axis print time of 10 minutes. Experimentation will be necessary to determine the ideal size. Both metric and SAE files are available for download.
