Ramps 1.4 + Mosfet Case

thingiverse

This is a custom build featuring an Arduino Mega paired with a Ramps 1.4 controller and a MOSFET for regulating the heated bed's temperature. A robust 80mm cooling fan is mounted at the top of the enclosure, ensuring optimal airflow. To securely fasten the MOSFET and Arduino to the bottom component, I employed four 3x10 screws accompanied by washers for added stability. The upper and lower sections are joined together using six 3x20 screws. Notably, the M3 nut slots were deliberately undersized, allowing me to heat the nuts and precision-fit them into place after they had melted the surrounding plastic.
