Enhance: Add .dwg Bottom/Top Plates for Acrylic Manufacturer Service

[Dafeigy]

What feature would you like to see? I want this fantastic keyboard supports transparent acrylic bottom/top plates in order to display the inner structure of the keyboard while providing sufficient protection to the PCB. Acrylic Plates are also cheaper than FR4 PCBs, so I would appreciate that it can be supported.

Are you prepared to help? I am willing to do this. I Opened a PR that contains related files and have been verified by myself. Please let me know if any information is required.

By the way, this repo is really a nice work. Thank you for you contributions~
