07 / A SMALL CONNECTION
Build a QR code with separate base and raised modules for two-colour printing.
Print the modules in a dark colour on a light base. Keep the four-module quiet zone clear and test scanning after printing.
This generated model has not been physically test-printed. Inspect fit and thin details in your slicer.

3MF keeps named parts aligned. It does not include filament assignments or printer settings. Choose a file format →
Open the file in your slicer, check the scale and thin details, then choose settings for your printer and material.
FROM PREVIEW TO PRINT
Generate a raised QR pattern on a supporting plate, with an optional key ring. Download STL for combined geometry or 3MF for aligned, named parts. Set the colours and printer profile in your slicer. The model includes a four-module quiet zone around the code. Successful scanning depends on physical contrast, module size, lighting and the camera; a valid digital pattern is not a guarantee that every print will scan.
Check the text before generating a large batch. The code stores exactly the supplied content; it does not shorten links, monitor destinations or provide a dynamic redirect service. Include the URL scheme when you want scanners to recognise a web address. Try the longest row at the planned plate size before using that size for every order. A four-module margin is reserved around the matrix, with a tiny overlap on raised squares to keep diagonal contacts printable. Keep decoration out of that area. Always test the physical result after colour assignment, slicing and printing, since a correct digital matrix alone does not verify camera readability.
These are model settings to test, not a validated printer profile. Check the result with your own material, nozzle and slicer.
| Setting | Start with | Why |
|---|---|---|
| Plate size | 55 mm | A starting footprint; dense patterns need more space. |
| Base thickness | 2 mm | Provides a flat support behind the code. |
| Module height | 0.8 mm | Makes a short raised pattern suitable for a colour change. |
| Error correction | H | Offers more redundancy while potentially increasing pattern density. |
Check colour contrast, quiet-zone clearance and the smallest printed squares. Use a shorter URL or a larger plate.
Inspect the slicer’s top view and choose a larger size. Redundancy does not repair a design in which many neighbouring squares are fused.
The encoded text is static. A linked destination may stop working, so use a URL you control for long-lived prints.
The printed pattern cannot be edited. If it links to a URL you control, you can change the page or redirect at that URL.
You can preview the first three QR rows from a CSV and check each destination. Batch downloads are not available yet. Use the single-model tool for individual STL downloads for personal use.
No. STL contains geometry only. Plan a filament change in your slicer and print dark QR modules on a light base. 3MF keeps the named parts aligned; assign their filaments in your slicer.
