Summary

• Fits actual SD card size
• Increased number of slots
• Design to minimize material consumption
• Increase the thickness of the bar for the hinge (+0.2mm)
• Adjust the position of the lid and the body so that they are well separated after printing(+0.15mm)

All of the above were applied from the beginning, only explanations were added
After printing, separate the lid and the lower part of the body with a knife (be careful not to cut the hinge bar), and when moving the lid for the first time, do not apply excessive force and move it up and down little by little to expand the operating range.
