The document compares specification data for two parts, the Cover Printer and Housing Upper, that are used in the Canna/Caviar printer. It analyzes the dimensional tolerances to assess the risk of the parts getting stuck during assembly. For the outside dimensions, there is a 0.2mm gap between the maximum and minimum, indicating low risk of getting stuck. However, for the inside dimensions, there is an overlap of -0.84mm, showing a risk of getting stuck during assembly. Actual measurement data from 30 samples of each part was also collected, finding a 0.23mm gap between minimum inside dimensions, but a potential defect rate of 21.4% during assembly.
