I saw a similar model to this a few months back and decided to design my own with a little twist. I added my career field logo onto it “3E3” which just so happens to have been adapted by the Memphis Grizzles on one of their new jerseys.

This is a super easy print with low infill and (16) magnets. Supported magnets are 6mm x 3mm. Tight insert areas so no glue is necessary.

I did a pause at the start of layer 20 so you can insert the magnets. Layer 20 is where the print starts to cover the magnets so it's a perfect spot.
