The handwired Powerspill, designed by Sandalmoth, is yet another Dactyl-like split with keywell.
My first design had the keys just a bit too close together and a thumb angle that was too steep for my hands. I also decided to add another row, as I find that it's pretty easy to reach and didn't see the harm in having it – Sandalmoth.
Initial layout created via OpenSCAD, design done in Blender.
Design considerations
The stagger is "a mix of vertical and back to front".
Pinky keys are slightly closer together than the others
Columns are flatter on the far end than on the close end.
The thumb cluster angle is reduced compared to previous designs.
Pitch is 17.5 mm vertical (16.5 for pinkies) and ~19 mm horizontal.
The author found that he doesn't really use his pinkies for the number row, so two keys in the top row are positioned for the ring finger – that's why the unusual shape.
