#Ender 3 Front Case Designed Specifically for BTT SKR v1.3 + RPI3 for Running Octoprint / Klipper I've Searched Everywhere and Found Nothing, So I've Made My Own **Read All Instructions Carefully** To successfully install this case, you'll need some tools and other bits. **Print Orientation & Materials** The base and lid are oriented correctly for printing. It will take 4-6 hours to print each part. Recommended materials are PLA+ or PETG. **Hardware Specs:** This case is designed specifically for the BTT SKR 1.3. Stepper drivers must be TMC2208 or TMC2209, both options will run in UART mode. The Raspberry PI 3B is also required. Two 4010 fans are needed, I run them in series at 12V for quieter operation. A LM2596 voltage stabilizer is used to provide 5V for the RaspberryPI. **RPI <-> SKR 1.3 Connection Diagram:**  Additional configuration is needed on the RPI3: 1. Add "*dtoverlay=pi3-miniuart-bt*" to the end of /boot/config.txt. 2. Delete "*console=serial0,115200*" from /boot/cmdline.txt. 3. Reboot the RPI. 4. On Octoprint interface, Settings-->Serial Connection-->Additional Serial Pots, add "*/dev/ttyAMA0*". 5. Use the port we added to connect, it's highly recommended to use 250000 baud rate. **Bits Needed:** 1. M3 Button head screws kit. 2. M3 nuts, standard DIN934. 3. M3 tap for making threads. 4. Connection to frame via M3 T nuts, can be printed - https://www.thingiverse.com/thing:3050607 **Revisions Tracking:** 19.04.2020 - Wiring diagram for RPI <-> RPI added. I'm Happy to Modify or Adjust if You Need Something Else. Happy 3D Printing!
