Raspberry Pi (3 or 4) Case for 5-inch Touchscreen

thingiverse

**BREAKING NEWS**: A brand new XL version of the case for a 40x40x10 cooling fan is now available, featuring large-diameter screws or rubber isolation plugs supplied with the fan. This case is specifically designed for the Raspberry Pi 3 (Model B or B+) or 4, and comes equipped with a 5-inch capacitive touchscreen display. The display uses the Pi's "DISPLAY" connector and a ribbon cable, as shown in photo 2. It can be found on Amazon under various names, including OSOYOO, Kuman, and Longruner. This is not to be confused with the resistive touchscreen that uses the GPIO and HDMI connectors; for that, you'll need another case like this one. The case has ample space inside for a 30x30x10mm cooling fan, and removable bumpers (feet) on the bottom allow for airflow to the fan. I purchased [this fan](http://www.amazon.com/dp/B076WWR5PM) on Amazon, which turned out to be extremely quiet. Adding a 27Ω resistor in line made it almost completely silent while still providing airflow. ## Components * `Case5C-Box-Pi3-v2.stl` - The case body for Raspberry Pi 3. * `Case5C-Box-Pi4-v2.stl` - The case body for Raspberry Pi 4. * `Case5C-Faceplate-v2.stl` - The faceplate for both bodies. (See Revision History below.) * `Case5C-Bumper-5mm-v1.stl` - A 5mm bumper (foot) to make room for airflow under the case when using a cooling fan. You will need four. * `Case5C-Bumper-2mm-v1.stl` - A thin 2mm bumper. You will need four if you do not install a fan. * `Case5C-Bumper-8mm-v1.stl` - An extra-high 8mm bumper for more airflow. ## Printing Both boxes print right-side-up, the faceplate prints face-down, and the bumpers print right-side up. No support is needed. I used 0.20mm layers on everything. For the bumpers, a flexible filament like TPU or soft PLA makes them more skid resistant. ## Assembly Install the bumpers first. They screw into holes on the bottom. They are a very loose fit, but snug down securely when tightened. Install the fan using M3-16 screws and nuts. A fan is not mandatory, but helps a lot. Install the Pi using M2.5-8 screws. There are four screw holes, but any two will be secure enough. The front ones are short and will not take longer screws, so use the others if you don't have 8mm screws. If you want to use the Pi's camera cable, photos 5 and 6 show how to make it fit. Connect the display using the cable that comes with it. **NOTE:** The cable is not interchangeable with camera cables, no matter how much it looks like them. Put in the display and snap on the lid. The display goes on with no twist in the cable, and the connector on the back sits above the Pi's USB ports. ## Revision History * 18 Dec 2019. First release. * 27 Feb 2020. Redesigned fan grill to produce less noise, more airflow. * 15 Nov 2020. Added Fusion 360 and STEP files for your modding pleasure. * 19 Nov 2020. Added 1mm height to faceplate to make touchscreen a better fit. Original faceplate is still available.
