This is a tolerance/gap and dimensional accuracy test, covering gaps ranging from 0.1mm to 0.5mm. After the printed part is removed from the heat bed, the indentations at the bottom demonstrate the progression of tolerances. The wide end measures 0.5mm, while the narrow end measures 0.1mm. Accordingly, the gaps are 0.1mm, 0.2mm, 0.3mm, 0.4mm, and 0.5mm. Each pin has a diameter and height of 10mm, allowing you to use a caliper to measure its dimensional accuracy. If you wish to test the dimensional accuracy of the holes, their inner diameters are 10.2mm, 10.4mm, 10.6mm, 10.8mm, and 11.0mm respectively. Thank you for choosing my model for printing! Be sure to use a <0.4mm slicing gap closure radius!!!
