The CRX is just like the CR-10S Pro, but with dual extruders! Like the Pro, it adds cool features like automatic bed leveling and an integrated touch screen, moving the electronics into the base makes it difficult to enclose. If you just stick it in a big box the electronics are going to get very hot. The metal 3D printer base already has a 40mm fan, but when enclosed, the fan just circulates hot air
This lightweight enclosure was designed to be worthy of the CRX by adding an 80mm electronics cooling fan to pull fresh air through the electronics case's vents and out the back without affecting the hot air inside the enclosure.
