This 3D printer test model is designed to evaluate the key performance aspects of the printer, including overhangs, bridging, overflow, first layer detail, roundness, and overall dimensional accuracy. The model is shaped like a small bed-type ejector printer, combining various challenging features in a compact design. It includes a sloping surface for testing overhang capabilities, a small gap for testing bridging performance, fine details on the base for evaluating first layer adhesion and accuracy, a circular element for verifying roundness, and a precise measurement section for checking dimensional accuracy. This test model is ideal for
