Sweet article on tested about HuB http://www.tested.com/tech/826501-custom-keyboard-spotlight-hub-keycap-profile/
HuB is a custom keycap profile that can most simply be described as a cross between cherry and DSA profiles. The base set includes support for many layouts including but not limited to - 104, 1800, WKL/HHKB, MiniVan, BananaSplit/DZ60, and Planck/Preonic.
The goal is high at $500,000 but the reason for that is creating molding and process that will allow us to produce very high quality keycaps for a very low cost. We are looking to bring the cost of custom keycaps down considerably as well as decreasethe turnaround time so that we can get them faster.
This is a very ambitious project, but with the support of this community behind us, we know we can make something truly awesome.
