CONGRATULATIONS! You designed and built your own keyboard. Well done!

Follow up / BONUS videos:
The follow up videos are not needed to build your keyboard. However I still would like to create them as they can be helpful. So when I have time or if this tutorial gets more views I will record them.
- BONUS: Customizing software for your QMK keyboard
- BONUS: How to add a custom image on your case / box
- BONUS: More details about 3D design (if enough people are interested I can make additional videos about how to design a nice enclosure, keycaps, knobs, etc ...)

If you would like to see the BONUS videos, please let me know in comments.
