Seal Carving Knife Case

This is a small, portable case for ordinary seal carving knives. It can hold three sizes of knives. My usage may be less frequent, so I've also included a case in the files without dividers that can be used for other small items of the same length.

External length, width, and height are 16CM×2.5CM×1.7CM
Internal length, width, and height are 15.8CM×2.3CM×1.3CM

I used translucent PETG from Top Bamboo for the outer shell, and TPU for the inner lining to prevent the knives from piercing the shell.

The case requires four magnets, 5mm in diameter and 4mm thick strong magnets, inserted from the side. I've tested it with translucent PETG from Top Bamboo, Easylife PLA, and Tianrui PLA, and they all fit snugly.
