This is the right half of my first custom design. Not available yet as its still in prototyping phase.

Features:

• Fully wireless, running ZMK
• Case with fixed tenting angle (not shown in the picture as I am currently designing it)
  • Provides space for large battery
  • Bottom-facing MCU, here a Seeed Studio Xiao
• Reduced pinky keys
• extra keys below middle finger column and next to inner column
• thumb keys aligned with grid (for me, this was the most comfortable position anyways, your mileage may vary)

Basically a 42 (-2) keyboard: One pinky key less and the 6th column has been moved to more ergonomic positions (no pinky stretching or hand bending outwards)

Pic shows the right half with MBK Legends keycaps along some custom keycaps made with FKCaps’ custom keycaps generator. I am using a slightly modified Colemak-DH layout where I Q and Z to the left and all punctuation to layers so the left pinky only has to operate a homerow key (and caps word / num lock).
