This Fusion 360 parametric model lets you create and customize your own stand for any QR Code.
Ready-made 3MF files are available for those who have created their own QR Code using my "Ultimate QR Code Generator: Text, Wi-Fi & More" model (fully customizable online!).

If you want to use existing print profiles, the QR code dimensions must be 50, 60, 70, or 80 mm.
The optional label(s), if included, must be 8 px in size.

The default settings should work well for most printers (I have a Bambulab A1 Mini).

If not, simply change the “tolerance” variable, which indicates the "clearance" the QR code will have in the stand's fit.

To attach the QR Code to the stand, you have a wide choice:

1. You can settle for the natural fit between the QR Code and the stand
2. Use a small amount of glue
3. Use a double-sided tape

The choice is yours!
