The model itself is good, printed at an angle, and the buckle has excellent layer adhesion. However, for filaments with poor overhang performance like ABS, if printed directly, the steps on the round holes are difficult to print, and the ceramic fitting will not fully seat due to overhang printing issues. Therefore, some steps were removed by Boolean operations to increase printing success rate, and the arrow pattern at the bottom was removed

The final image shows the difference between the original version and the optimized version on materials with poor overhangs like ABS

For the ceramic insert, choose one with an outer diameter of 3.9, a hole of 2.3, and a total height of 6, refer to the image below. It is recommended to buy a few extra, as if you bought too few previously and they broke, you would need to repurchase them
