Fan cover for Ender 3 all in one, universal rear electronics case

A protective shield for the right side of the enclosure crafted by TeachingTech, featuring holes specifically designed for an 80 mm fan. Please note that a 25 mm thick fan will not fit within this configuration; instead, use a 10 mm thick fan (measuring 80x80x10 mm or 8010). The Y-axis will inevitably collide with the fan if you attempt to utilize one with a 25 mm thickness. To power the fan from a 24v source, I employed a buck converter, similar to this one: https://www.aliexpress.com/item/32273602712.html. This effectively reduces the voltage to 12v or lower, allowing for a slower fan spin. Mount the fan so that it draws air out of the enclosure.
