Conference Badge
A custom name badge designed in Fusion 360 for conference wear: a 114 × 161 mm framed face with detail banding around the border and a recessed center field.
The QR code is a separate 77.5 mm plate with the code modeled as raised geometry — print it in a contrasting filament and it scans straight off the badge, and the code can be swapped without reprinting the whole thing.
