3D Model

A4 Revolution Brooch Thanks to Wu-Yue San-Ren’s idea, I made this 3D model for the A4 Revolution Brooch, Wu-Yue San-Ren’s and my studio’s names are engraved on the back. anyone who has a 3D printer please test it and give me feedback if there is any issue. You can download different files as needed. Please refer to the numbers at the beginning of the models’ names, the 4 models are on my page https://sketchfab.com/chiaofan: 1. Brooch without pin (for mass production, the pin has to be installed manually) 2. Brooch with pin open (for non-metal copies production, e.g. plastic 3D printing) 3. Brooch with pin closed (for rendering, may not be good for 3D printing) 4. Pin (just in case if anyone is interested)
