Squeezebox Keyboard v2105

Split ergonomic computer keyboard. Features adjustable per-finger column stagger, adjustable per-finger splay angle, independent and easily replaceable components. Designed to hold Kailh Choc key switches using Kailh hot-swap sockets. Designed for an Elite-C microcontroller.

Slicing Instructions

See the include screenshot from Prusa Slicer for orientation of parts on the build plate.

• Print the keywells with their narrow edge on the plate. A skirt may help but mine were mostly fine with no skirt.
• Print the pillars with the cylinder part on top
• Print the thumb cluster like a food serving tray with the bottom on the plate
• Print the PCB housing with the face where the connectors go face down on the plate
  • You'll need to print one of these as-is and the other one you need to mirror this along the Y axis before slicing to get the symmetry right

I use 0.2mm layer height and a 0.4mm nozzle
