Awesome design, perfect fit on my HF Calipers - batteries will now last months instead of weeks (provided I remember to use the shutoff)

I have an old Harbor Freight digital caliper. I thought this battery saver design had many attractive features over the others, so I thought I'd give it a try. Unfortunately, the HF style of caliper does not have a slot for the battery saver to enter. The HF style of caliper at first glance looks like the one in the pictures above. But upon further inspection there is an obvious difference. The one above has a locking set screw directly above the blue mm/inch button. The HF style has the blue button offset to the left of the lock screw by 3/4" (15mm). Image attached.

It's a thoughtful design that prints well. But to save others from wasting their time when they have the HF style of caliper, I wanted to pass this info along.

I see a cover above the battery compartment. If you remove that cover, does it not give access to the battery like the others? It looks to be in the same position as mine.

The data port cover does come off like yours. But my version has a different internal design. Access to the battery contacts is completely blocked.

Brilliant! Thanks for sharing!

Thank you for the great idea!
