HHKB Service Station

 HHKB Service Station

When servicing an Happy Hacking Keyboard to lubricate its sliders, enthusiasts would often use two thick coffee books to raise the plastic enclosure. Suspending the keyboard helps with the removal all the components and reassembly.

The goal of the service station is to lock in place the enclosure and improve the process by reducing the desk space required and the chance of knocking the keyboard out of one of the platforms. A fullsize and lite split version (for smaller printers) are  provided.

A mini tray has also been designed to store the fasteners of an HHKB Professional Classic.
