Mantaray Ergonomic Keyboard Case

This is the case for the Mantaray, an ergonomic mechanical keyboard I designed.

The upgraded version of this project, the Mantaray Pro Wireless, is now available! You can pick one up either assembled, or as a kit. The 3D case files are available on MakerWorld. 3D files for mounting accessories coming soon!

Want to make this project? Consider purchasing the keyboard PCB from my shop! It's a great way to get an affordable PCB for this project while showing your support for my work!

The keyboard is inspired by the ZSA Voyager and features:

• low profile choc v1 switch support
• ortholinear, column staggered layout
• OLED display to view caps lock status, currently selected layer, and WPM count

How to build:

Follow the written build guide on my GitHub, or check out my YouTube channel for a video guide.
