Balance PE foam
Cross-linked PE foam for the Balance keyboard by Cannon Keys
Diagram shows standard supported layout, but stepped caps is also supported.
For clarity: supports the 1.25u/1u/1.25u/7u/1.25u/1u/1.25u bottom row (because its called the Balance, after all), either stepped or regular caps, regular backspace, regular left shift, ANSI enter, and 2u + and enter keys on the numpad.
A special thanks to mcheddadi. Without his research and contributions, we never would have been able to offer this product to the community.
