Minibot Ultra 3D Printer (ERRF2019)

thingiverse

I've designed this ultra-portable 3D printer to bring to ERRF2019. Many people have enjoyed it, and now I'm making the design open source for you guys. As every component fits in a very small space, the assembly process is incredibly time-consuming. The use of Nema 11 motors in the X and Y axes limits the maximum speed at approximately 35mm/s, or else the motor temperature gets extremely high. The full assembly file in Fusion 360 is available to download at: https://a360.co/2qiTI5F Unfortunately, the worst thing is that the OLED 1.3-inch smart controller mini LCD has been discontinued in China (I guess), and I bought mine from https://pt.aliexpress.com/store/product/Reprap-Ramps1-4-MKS-12864OLED-display-1-3inch-smart-controller-mini-oled-screen-oled-3d-printer/1047297_32810915698.html?spm=a2g03.12010608.0.0.148d1734dthpOv in 2018, but it's no longer available. If someone knows where to find it, please let me know! I advise you not to start this project unless you have the OLED panel.
