This is a replacement for the sliding part of the calipers from Batesville that are used to measure the elbow to elbow width of decedents. It's printed in two parts, and must be joined around the ruler.

If the stop is broken off of the end of the ruler, I've been gluing a clasp from a zip tie to it to keep the slider from coming off.

Aron Alpha works well for joining the parts, and for attaching the end of a zip tie to the far end of the ruler if necessary. You might have to sand the parts for better adhesion.
