120mm fan air guide

thingiverse

This is a crucial component used to draw cool air into a DIY printer enclosure for a Creality CR-10S, hopefully preventing overheating.\r\n\r\nI deliberately avoided creating a "wood stove" effect in case of fire by locating all air inlets and exhausts at the lowest possible points in the enclosure. This part is the central component of the cool air intake system. Its primary function is to draw in fresh air from the bottom side of the enclosure and redirect it upwards. To ensure even distribution, a stirring fan will be installed to circulate the cool air across the top of the printer. Air flow will be precisely controlled by an Arduino temperature sensor, which will regulate the operation of two fans: 120mm PWM (4-pin) and 80mm PWM (4-pin).\r\n\r\nThree slots are designed into this build.\r\n- An optional 80mm fan for exhaust purposes\r\n- A 120mm fan for intake duties\r\n- A 120mm filter, currently equipped with just a simple foam filter
