Made this to hang in V-notch of a stand I store some things on. The hanger can be easily removed or modified in slicer software, if an alternate method is needed. Should one need a tutorial for that, here is a short video showing how that can be done... https://odysee.com/@HOWIC:d/Customize-3d-parts:9
I have also include a step file if anyone prefers to make modifications that way.

The body of my caliper is 30 mm wide. I made the gap of this holder 32 mm.

There is 9 mm extending out to support the jaws, and 8 mm high stopper in front to hold them in place.

The hanger on rear extends out 7 mm.

For those that do not want to sign up to download this, I have made it available on my Odysee channel...
