Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

Hi all,

I want to create a custom computer keyboard plate that is choc-switch spaced.

Are there templates for the slot that a choc switch would clip into (correct width, height & any angles ) that I could incorporate into a keyboard case layout? Plan would likely be to print a blank pcb with the cutouts, so something I could pull into KiCad would be ideal.

Note: cross-posted with slight alterations to 3DPrinting.

I modeled this based on publicly available 2D drawings of choc switch and MBK keycaps. (only the tab with 1u keycap is accurate, the other sizes are just extrapolated from 1u). https://cad.onshape.com/documents/de7f3deb0f607e27e1e3b0a5/w/a5d7d9590f3d54af6134a42c/e/13311f5788e147dc81e0db27?renderMode=0&uiState=64a150bde27a2f1cb2146061

Looks like your plate needs to be 1.3mm, and the square cutout is 13.8mm²
