EchoCom

Borderlands 3 - Echo Device

This repo contains all the needed files to create your own 3D printed Echo Com from Borderlands 3. I put lots of images in the repo so the size got quite big, sorry for that 🤷‍♂️.

If you need additional information or have any questions please just open an issue and I will try to answer them 😀. And please, if you decide to give it a shot and you use my model, please please send me pictures of the result! :) Just open an issue here to show off your amazing work.

Printing

• I printed all opaque parts with PLA filament with 0.15mm layer height.
• For the electronics version, the inner projector part was printed with "transparent" PETG filament to let the light of the LEDs pass through.
• I Recommend printing more or less everything with full support to make sure all the complex parts get printed properly.
• Removing the supports is quite easy with this model.

Components for the electronics version

• 4" TFT Display
  • I really recommend buying exactly this one as the 3D model is designed for exactly this product.
  • It was the only display I found that had the correct size for the EchoCom.
  • You have to remove the pin headers from the backside for it to fit into the model. The required wires then can be re-soldered with a thinner footprint.
• Custom PCB
  • You can find the KiCad project and a finished plot of the PCB in the pcb folder.
  • Use a service like JLCPCB to have it manufactured or you can of course do it yourself :)
• Electronic Components:
  • 1x Atmega328P-PU
  • 8x Push Button
  • 2x 22pF ceramic capacitors
  • 1x 16MHz Crystal
  • 3x 100nF foil capacitor
  • 1x 10K Ohm resistor
  • 2x Digital RGB LEDs (eg WS2812B) (one or maybe more than two might also work for you)
  • 2x Screw Terminals (optional, you can also solder the power wires)
  • Pin Header (optional, you can also solder the wires, but I recommend the headers!)
    • 2x 3-pin
    • 2x 5-pin
    • 1x 6-pin
• Some sort of power source (I have not yet figured this out)
• Wires (with correct heads depending on your pin headers)

Code

The code is very, very unfinished! I recommend Visual Studio Code to edit the code. The code is a PlatformIO project, so I recommend the PlatformIO extension for VSCode.
