KingJim Business Card Holder

This model is a replica of a Jin Gong card holder (though I'm unsure about potential legal implications, so this model is for sharing, learning, and exchange only; commercial use is prohibited XD)

Functionality verified. Recommended slicing parameters: 0.2mm layer height, 2 walls, 100% infill, ironing enabled

All you need is a 3mm rubber band, easily purchased on Taobao.

I'm exploring better methods for quickly connecting the rubber band ends without knotting, avoiding unsightly bumps—it's simply not elegant. Stay tuned for future updates.

For easier assembly, please refer to the following transparent image

Use a square knot for a flatter result. See the diagram below for reference

Chamfering with a chamfer tool is recommended for smooth edges
