OctoDash Enclosure - RPi4 and BTT Pi TFT50 v2.1 screen
Description
This as a big overhaul even from 6ROM7's changes from strangecalling's design. I basically started from scratch but with heavy influence from both of them. My problem with 6ROM7's design is that the v2.1 screen from Big Tree Tech differed just enough that it didn't fit nicely and I didn't want as complicated of a power solution. This does require understanding of how to setup a Raspberry Pi for OctoPrint/OctoDash and some very basic wiring. I have 2 enclosures and 2 back covers. 1. Mounts to the top of a rail and allows USB cable pass through with the top mount [USB Cover](https://www.thingiverse.com/thing:6744582) 2. Mounts to the side of a rail and uses the side mount [USB Cover](https://www.thingiverse.com/thing:6744582) 3. One back cover has a hole for cables and one doesn't. Can modify the one that doesn't in the design program of your choice or just cut a hole. See Print Settings about making the back be an open grill. I also created this [USB Power Plug](https://www.thingiverse.com/thing:6744574) to power the Pi off the printer. <b>Items needed:</b> * [BTT Pi TFT50](https://amzn.to/4cG71hY) * [Raspberry Pi4](https://amzn.to/3yV1yFZ) * [90* USB C Cable](https://amzn.to/3Z1OAB0) - to power the Pi4, can use a shorter cable or a low profile 90* adapter but these are good and cheap * [Noctua NF-A4x20 5V](https://amzn.to/4714HR8) * [Jumper Cables for RPi](https://amzn.to/3Z1wCOV) * [90* USB to USB C](https://amzn.to/3ABBY9I) - use the down angle * [USB C hub](https://amzn.to/4dYvL5V) * [USB Power Blocker](https://amzn.to/4715q4O) * [90* micro USB cable](https://amzn.to/3z2q73O) - same as what is listed in my [USB Cover](https://www.thingiverse.com/thing:6744582) * [M5x10 flat head bolts](https://amzn.to/3AQ0kwf) * [M5 t-nuts](https://amzn.to/4e0evgA) * Optional: [M3x8 bolts and nuts](https://amzn.to/479NANm) * Optional: [RPi4 heat sink](https://amzn.to/3YUsvEu) <b>Setup/Wiring:</b> 1. Print your preferred mounting option for the enclosure and a back cover 2. Mount your RPi4 to the BTT Pi TFT50 screen with the included screws (or the longer black screws from the heat sink if you bought that) and connect them together with the included DSI cable 3. Connect the USB to USB C adapter to the Pi4 (you won't be able to once it is mounted) 4. Cut the male end off 2 jumper cables 5. Use the included pigtail and wire connectors from the Noctua fan to join the jumpers to the pig tail 6. Install the jumper cables to the appropriate pins (need 5v and ground) on the Pi4 7. If doing the side mount [USB Cover](https://www.thingiverse.com/thing:6744582), attach the enclosure and side cover together with 2 M3x8 screws and nuts with the screws going from the inside of the enclosure 8. Install the screen in the enclosure with the screen buttons to the top using the included screws from the screen 9. Plug the USB C hub into the 90* adapter and plug the Power Blocker into that, push the USB C hub to the front of the enclosure under the Pi/screen 10. Mount the enclosure with the appropriate amount of M5x10 screws and M5 t-nuts 11. Plug in 90* micro USB cable from printer to the Power Blocker 12. Plug in 90* USB C to Pi4 for power 13. Install fan to back cover using included screws, have label facing inwards 14. Plug fan into jumper cable pig tail 15. Install back cover with 6 M3x8 screws, make sure to feed the USB cable to power the Pi out the hole at the bottom of the cover 16. Provide power to the Pi (convenient way is with the [USB Power Plug](https://www.thingiverse.com/thing:6744574) I designed) and the printer
