Minibot Ultra 3D Printer (ERRF2019)

thingiverse

I've designed this Ultra portable 3D Printer to bring to ERRF2019. Many people enjoyed it, I have to make this design Open Source for you guys. As the space is very limited for every component, the assembly process is very time consuming. The use of the Nema 11 motor in X and Y axis limits max speed at ~35mm/s, or the motor temperature gets very high. Full Assembly file in Fusion 360 available to download at: https://a360.co/2qiTI5F The worst thing is that the OLED 1.3inch smart controller mini LCD is discontinued in China (I guess), I have bought mine at 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 and it's not available anymore. If someone know were to find it please drop me a line ! So I advice you not to start this project if you don't have the OLED panel.
