Here is a QR code and stand. Both the QR code and text are fully customizable. An AMS is not needed, you just need to switch filament colors part way through.

Please download the Stand file through this page, otherwise I will not be credited any downloads. The QR code generator can be found here. Thank you for understanding.

Print Settings:

• Filament: Black + White PLA
• Layer height: 0.2mm
