V393 to V303 Button Cell Adapter

thingiverse

With my caliper's (V303 size) battery dwindling, I sought a replacement but found only smaller button cells (V393) unused. To make it work, I designed an adapter with a crescent shape to fill the gap and hold the smaller battery against the bottom and side contacts.

Print raftless and clean off excess plastic. Adjust fit if necessary to keep your callipers functioning while reducing battery waste.
