Thanks, I wasn’t aware the TinkerCAD project URLs are available to share yet. I’ve changed the URL to the Thingiverse project I used for the Navio 2 case top, renamed and updated that to include all the models: Emlid Navio Case by CodeChief - Thingiverse
Individual TinkerCAD design URLs (which should work):
Navio 2 Top: Tinkercad | From mind to design in minutes
Navio Plus Top: 3D design Navio Plus Top | Tinkercad
Navio Base: Tinkercad | From mind to design in minutes
