Share an Itembox QR

Itembox codes only. AutoBuild blueprints go in the build section.

How do I get the QR image?

In game, hold L to open AutoBuild, pick your design in the history, then press X to send it to Zelda Notes.
On your phone, open the Nintendo Switch App → Zelda Notes → AutoBuild Sharing.
Open your design and save its QR code image (or take a screenshot).
Upload that image below. Keep the whole Zelda Notes card: that is what looks best on the site.
