The badge material seemed pretty thin near the lanyard attachment point, so I designed this holder instead. The badge is easy to put in, and take out if necessary, but should not fall out due to the outer lip and snug fit.

Printed with PLA at .2mm layer height and snug supports from the print bed, just for the top and bottom badge ledges. I did a color swap at layer 16 to make the letters more visible.

I included the main file types fusion allowed me to export, so you can put your name in the top slot.
