This bin is made of cardboard (up to 1.7 mm thickness) and small 3D print parts to minimize material waste. If you prefer a sturdier version and don’t mind using more material, you can print the “paper box” file and glue all the parts together for added rigidity.

Cut sizes: 9.8mm (front) x 9.4mm x  9.8mm x  9.4mm

It uses two 20×10×2 mm super-strong neodymium magnets, which you can find here:  https://s.click.aliexpress.com/e/_c4q1Zfgt
