Pen Holder & Case

A simple and easy-to-assemble hinged pen case. In the closed state, it is a parallelogram with rounded corners, making it convenient and safe to carry. Measuring 194mm*50mm*72mm, it can hold various stationery items shorter than 15.5mm. When opened, it forms a triangular shape, functioning as a pen holder for easy access and space saving.

It uses magnetic closure with a total of 12 strong magnets. In practice, only installing the 4 magnets along the top and bottom edges is sufficient for daily use, ensuring a secure closure that won't open due to shaking. Installing all 12 magnets may result in excessive magnetic force, making it difficult to open. It is recommended to install only 4 short magnets. Specific dimensions: short magnets 15mm*2mm*1mm, 4 required; long magnets 20mm*5mm*1.5mm, 8 required.

Any printable filament can be used for the shaft. During assembly, tools can be used to slightly expand slots and holes as needed.
