v4n4g0n inspired, 3d printable keyboard

Materials

1. 3D Printer
2. Filament (PLA)
3. 1N4148 diodes (one for each switch)
4. Switches
5. Keycaps
6. Stabilizers (6.25u Cherry style for space bar)
7. Micro-Controller (I used a Pro Micro with USB C, but others with ATmega32U4 will work)
8. Nuts and Bolts (12 3M x 16mm hex screws and nuts)
9. Wire (I've had the most luck only using 20-28 awg solid core wire. I use the soldering iron to remove insulation.)
10. USB Cable (USB C to USB A in my case)
11. Soldering Iron (A basic soldering iron will do, quality does not matter too much)
12. Solder (60-40 rosin core solder works best)
13. Solder Sucker
14. Zip Ties (for securing micro-controller)

3d Print

1. Download the STL files from the releases section.
2. Slice the files using your preferred slicer settings. I recommend using:
   • a layer height of 0.2mm
   • printing at 90% infill
   • a brim for better bed adhesion
   • supports for bot parts
3. Print the following parts:
   • V4N_bot_left.stl (fits a wide range of micro-controllers)
   • V4N_bot_right.stl
   • V4N_top_left.stl
   • V4N_top_right.stl

Soldering

Rows

1. Place all switches into the top case pieces.
2. Put in space key Stabilizer (you'll regret having to de-solder later if you don't do it now)
3. Solder a diode to each switch, making sure the black side of the diode is facing down. Example image below:
4. Solder a wire at the end of each row of switches (this will go to the micro-controller).

Columns

1. Cut pieces of wire long enough to reach from the top of the switch to the micro-controller pins.
2. Solder the wires in the following configuration:
   • Tip: I like to burn away the insulation on the wire at the points where I want to solder.

Micro-controller

1. Solder wires to the micro-controller in the following configuration:

clarification:

the top row (ROW 0) should go to D3 on the Pro Micro, the second row (ROW 1) to D2, continue with the rest of the PINS diagram.

Programming

1. Download and install QMK Toolbox
2. Download the hex file k3yb0rg.hex.
3. Connect the micro-controller to your computer.
4. Open QMK Toolbox and flash the k3yb0rg.hex file to the micro-controller.
   • open hex file
   • check "Auto-flash"
   • make sure the correct micro-controller is selected (ATmega32U4 for Pro Micro)
   • press reset button on micro-controller (if available) or short RST to GND
   • wait for "Flash complete!" message
5. Your keyboard should now be functional open keyboard tester to verify all keys work: Keyboard Tester
6. If you want to customize the keymap or Wiring, you can use keyboard firmware builder, click upload and open the k3yb0rg.json file.

Assembly

1. Place the micro-controller into the bottom left case piece and secure it with a zip tie.
2. assemble the top and bottom case pieces together using the 3M x 16mm screws and nuts.
3. Place keycaps on switches.
4. Enjoy your new keyboard!

Layers

you can edit the layers using keyboard firmware builder or QMK Configurator. (Using the k3yb0rg.json file)
