Sidecar Ender 3 Electronics case

thingiverse

**Important Design Notes:** This design is specifically created for the SKR 1.4 motherboards and has not been tested with any other models; I do not believe it will be compatible with the standard Creality boards. Why It Exists: There are numerous electronics case designs available for the Ender 3, but none of them met my unique requirements. I wanted easy access to the electronics so that if a problem arose, I wouldn't have to disassemble the entire printer; simply removing the lid would suffice while the printer remained in place. As someone with experience building high-performance PCs, I was disappointed by the lackluster cooling and cable management found in most solutions. This design aims to address these shortcomings. The case is positioned at the side of the printer opposite the PSU, featuring a 40x10mm fan at the bottom (in the pedestal) that draws cool air in, while another 40x10mm fan at the top pushes warm air out, creating a chimney effect and directing an airflow stream across stepper motor heat sinks. This design is intentionally large for several reasons: 1. It provides enhanced airflow both above and below the motherboard. 2. It offers ample space for cable management. 3. There's room available (though no mounting points) for buck converters. The bulge in the case, accompanied by a "cable gate," is designed for individuals who prefer not to spend time meticulously crafting cables of exact lengths; instead, this feature allows you to securely tuck them away, preventing overheating and potential issues with the motherboard. This design was created specifically for an SKR 1.4 Turbo, but I suspect that the mounting holes are similar across most SKR boards (no guarantees); however, I do not believe it will be compatible with Creality's standard motherboards.
