This is the mount ring that holds the squares and the "rest" of the QR code:
Design Contest Entry for #3DPNSpeakerCover.
QR Code generated using https://www.qrcode-monkey.com/
Saved as SVG, scaled up the squares using inkscape and added "fake" squares around the edges.
Than import into Fusion 360 as well as an SVG for the logo.
When viewed with a QR code reader (e.g. camera on your smartphone), against a dark background (like a speaker), the QR code will redirect you to 3DPN's youtube channel.
Alternatively, you can create your own QR code and modify the design to link to your last.fm, spotify playlist(s) etcetera. The possibilities are endless!
