Configurable attachment loop
Move the loop to the top, right, bottom or left and adjust the outer and hole diameters.
QR CODE KEYCHAIN
Create a QR code keychain for 3D printing
Turn a scannable QR into a compact carry-ready object with an integrated attachment loop. Choose the loop position, tune its dimensions, inspect the model in 3D and run ScanSafe guidance before export.
The current generator runs in your browser. ScanSafe provides guidance, not a guarantee that every physical print will scan.
What you can do
Create a QR code keychain for 3D printing
Live physical preview
Inspect the complete keychain geometry and switch between 3D, front and back views.
STL or 3MF export
Run export preflight and download the current keychain in the format that fits your workflow.
COMPACT OBJECT CHECKLIST
A keychain gives the QR less physical room to work
Compact objects make density and mechanical clearance more important. The attachment loop should not force the QR itself below a useful module size.
Size the QR before the loop
Keep the scannable region large enough, then fit the attachment geometry around it.
Protect the quiet zone
The loop, border and decorative geometry should stay outside the clear margin around the code.
Check loop thickness and hole size
Inspect the printed load path as well as the QR; a scan-safe face is not automatically a durable keychain.
Test worn surfaces
Keychains get scratched and handled, so test the actual material and finish before making many copies.
How this workflow works
Start with a QR that fits the object
A keychain has less physical area than a wall sign or tabletop plaque, so QR density matters. Use the physical size control together with ScanSafe to watch module size and avoid shrinking a dense code beyond the selected print profile target.
Place the loop where it makes sense
The keychain template supports top, right, bottom and left loop positions. Top is the recommended default because it keeps the object visually balanced, while the other positions make it easier to adapt the model to a specific carrying or mounting idea.
Treat ScanSafe as guidance before slicing
ScanSafe reviews measurable QR and model conditions such as module size, contrast, quiet zone, base thickness and feature depth. It is not a guarantee that every physical print will scan, so final validation should still include your slicer, printer and a real scan test.

Frequently asked questions
Can I move the keychain loop to another side?
Yes. The current template supports Top, Right, Bottom and Left positions.
Can I change the keychain hole size?
Yes. Advanced object controls let you adjust the outer diameter and hole diameter of the attachment loop.
Can I export the QR keychain as STL and 3MF?
Yes. The template uses the same export preflight workflow as the other 3D QR objects and supports both STL and 3MF.
