Sip & Scan is a fully customizable QR code coaster that's actually functional. Print your WiFi password, contact card, Venmo tip jar, or any URL right into the surface, no app needed just scan and go.

Designed in OpenSCAD with the SCADQR library. Every parameter is exposed in the Customizer: diameter, border, drain dot seed, error correction, 11 QR types, and full Bambu Lab filament color presets for both the base and QR layer. Turn any drink into a link. 

Special thanks to xypwn for creating the qrcode scadqr library released under the MIT license.

Supported QR types: Plain Text · WiFi · Phone · VCard · Venmo · Cash App · PayPal · SMS · Email · Location · Calendar Event.

Print settings: Works best as a 2-color print with AMS — white base, black QR layer. Color swap happens at the base layer (default 2mm — layer 20 at 0.1mm). 

Recommended settings: — Layer height: 0.1mm or 0.12mm for crisp QR edges.

 No supports needed, print QR face up. 

Tips: — Keep qr_error_correction at M or higher for reliable scanning. Lower it to L if your message is long and the code comes out too dense. Change random_seed for a unique dot scatter pattern every print. Use coaster_filament and qr_filament dropdowns to preview Bambu Lab colors directly in the Customizer

Sip & Scan v2.0 coming soon with even more features.
