These parts were successfully printed and tested on a 3D printer without an automatic color-changing system (such as CFS, AMS, or similar), with no quality issues.

In fact, it is recommended not to use automatic filament switching systems, even if your printer supports them. The purge waste generated during color changes is significant, making the process inefficient. It only becomes practical if the print bed is fully loaded with multiple parts, helping distribute the material waste.

🔧 Fit Adjustment (XY Compensation)

Proper XY compensation adjustment is essential to achieve a precise snap-fit connection between parts.

Recommended approach:

Print a calibration piece before full production, or

Manually adjust XY compensation and print only two test pieces

This prevents unnecessary filament waste and ensures a perfect fit.

⚙️ Successfully Tested Print Settings

3 walls (perimeters)

4 top layers

4 bottom layers

5% infill — structurally sufficient

Orientation: print with the side face of the part placed on the build plate

No supports required

Using these settings, the parts achieve solid structural strength and precise interlocking performance.
