Ender 3 (And Pro) Octoprint Pi4B Case

thingiverse

This is a comprehensive enclosure designed specifically for users running Octoprint on their Ender 3 or Ender 3 Pro. The enclosure is an integrated solution that combines elegance and simplicity, making it perfect for those seeking a hassle-free experience. I'm particularly proud of this design because it's built with precision in mind. Every detail has been carefully crafted to ensure seamless integration with the Ender 3 series. The parts are designed with a 0.3mm tolerance, guaranteeing a precise fit when printed on a well-calibrated machine. Pre-prepared gcode is available for the standard case, but it's essential to note that print settings may vary for the Pro version. To generate gcode for the other parts, users can simply do so themselves. The enclosure should print flawlessly on a stock Ender 3, although I haven't personally tested it. Cura estimates a print time of 11 hours and 54 minutes for this part (0.12-0.28mm adaptive layers, 0.4mm nozzle, 50mm/s, 3mm retraction at 50mm/s, 3 perimeters, 15% cubic infill). To further optimize the printing process, I've created custom supports that significantly reduce print time. I highly recommend using these if you don't plan to use my pre-prepared gcode. To load the .3mf file into Cura, simply select it instead of the .stl file and ensure that "automatically drop model to the build plate" is turned off; this will prevent the supports from being misplaced. Key features of this enclosure include: * Two vents at the front for improved airflow and reduced risk of overheating * A slot above the USB 3.0 ports for routing PiCam cables, as requested by a user in the comments * Integrated support for a standard SD card adapter for users who prefer to keep this functionality * A removable lid via a snap-fit joint * Optional support for a 40mm fan for additional cooling (see Lid_with_fan_v2.stl), as well as a fan shroud (optional_fan_cover_v2.stl) * A slot at the back left for routing the USB-C power cable through, allowing it to exit the base where the wiring from the mainboard comes out Note for Pro users: I couldn't find a 3D model for the Ender 3 Pro and didn't have one myself to cross-reference. As a result, I had to reverse-engineer this design from other people's designs, which may not fit perfectly. However, I've taken an air-on-the-side-of-caution approach, so it will likely fit looser rather than too tightly. PLEASE provide feedback if you print this for yourself! I'll also be unable to provide gcode or 3mf files for the Pro version. Happy printing!
