About GenQRCode
GenQRCode is a general QR code service that also exports 3D files. On its STL page you choose from many content types, including URLs, text, vCard, WiFi, email, WhatsApp, phone, SMS, calendar events, geolocation and crypto addresses, then style the code and download it.
The same page offers 2D formats such as PNG and SVG next to STL, 3MF and OBJ. Design tools cover frames with text, logos, colours and templates, and the 3D export adds size, base and magnet hole settings. The site recommends a low code height of about 0.5 mm so shadows do not stop the code from scanning, and advises black and white designs for the cleanest 3D result.
Static codes and 3D downloads are free without an account. Dynamic codes that can be edited later and some content types need an account and fall under its paid plans.

- 6 x 2 mm N52 neodymium disc magnets (bulk pack)Buy 100+ for full baseplates; check the listing really says 6 x 2 mm, as 3 mm-thick magnets will not sit flush.
