Our grandsons love the Stem Detectives children books. Each book ends awarding a 'Stem Detective' badge in PDF format. Hence they asked if I could 3d-print the badges. The badge prints with a colour change for the actual logo.  A bit of clean up is required after printing as the logo tends to string a bit. I printed at 80% speed.

A separate clip should be attached using superglue. The clip I used was adapted from https://www.printables.com/model/141100-dove-tail-clip-for-badge
