I designed this 3D printable model for the Logitech MX Keyboard Adaptive Add-ons contest. It was designed with accessibility in mind for those who might have difficulty accessing a keyboard in certain positions.

There are 4 main positions in this design:

  • Hidden Position: Slides completely under the desk to maximize your room and keep your workspace clutter-free when not in use.

  • Extended Position: Brings the keyboard out to the ideal ergonomic distance for comfortable, everyday seated typing.

  • Standing Position: Raises the tray to an elevated height so you can maintain a comfortable typing posture while standing.

  • Flipped Position: Folds directly onto the desk surface for standard or laptop setups.

Some of the ergonomic and accessibility aspects include:
