Here is my Cosplay Caliper tool I designed after seeing Nikko Industries awesome video explaining how he made his with foam. I figured I'd take that same concept and make it 3D Printable.

I've also shared the Tinkercad file. Feel free to modify it further and share your tweaks!
Here is a video explaining the process

*UPDATE - I added a .3mf file for Bambu Lab Printers - Quick 1 hr print on the X1 or the P1P
 

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/h387ngVeYoE

Thanks for watching!

How I Designed This

Workflow

I initially designed the outline in Adobe Illustrator > Exported to SVG > Edited in Fusion 360 > Exported to STL > opened the file in Tinkercad and further modified the file for printing.
