Creality Ender 3 Pro - Raspberry Pi 2/3/4 + LCD Enclosure

Don't forget to LIKE this thing :) Raspberry Pi 4 01/10/2026 - Renamed files to reflect which Raspberry Pi version they are for. 30/09/2020 - v054 Added Step file 11/09/2020 - v054 (for Raspberry Pi 4) Added a version for Raspberry Pi 4 with internal mount points for an internal fan. Raspberry Pi 2/3 01/10/2026 - Renamed files to reflect which Raspberry Pi version they are for. 30/09/2020 - v042 Added Step file 04/09/2020 - v042 (for Raspberry Pi 2/3) Added a newer design that has bigger and angled side grills, both allowing more air to get in and also easier to print than the previous version. Also this version has a 1.5 mm thickness, compared to 1.2 mm of the previous version, which makes it sturdy, less wiggly. Though, it uses more material (52 g vs 60 g) but prints around the same time. Also I had to reprint it anyway, because I had under extrusion problems. 02/09/2020 - v035 - Initial Version (for Raspberry Pi 2/3) I don't recommend this version. Please use v042 for Raspberry Pi 2/3 This is an enclosure that I designed to go under the LCD display of the Creality Ender 3 Pro (probably will fit perfectly to Ender 3 too) that also holds a Raspberry Pi 2/3 and now 4. Later on, upon request, I'll add a Raspberry Pi 4 version too. DONE. Also want to create a version that has thicker walls. The current wall thickness is on the edge. DONE TOO. When mounting it to the LCD panel, you should use only 3 of the original screws. So one of the screws will not be used. I did it in that way for cosmetic purposes. Because the hole for the 4th screw needed to be in a place that makes it ugly. There is a pin that goes through the 4th whole. So the case will hold the LCD PCB properly. Printing is pretty straight forward. I designed it to be printable without any support. I included the FreeCAD file too. So you can remix it freely. May be one wants to make the Raspberry Pi 4 variant for me ;) DONE IT. Have fun!
