what i was trying to do
“I chose a steno layout because it forced a design problem I had not solved before. The key geometry is unlike a standard board, which meant modelling every keycap from scratch rather than adapting an existing profile.”
what broke
“The mechanical side went through many printed revisions before the tolerances held; fit and print technique were resolved by iteration rather than calculation. The electronics survived intact — no component lost — which I attribute to the time spent verifying the board in CAD before ordering.”
where i am now
“Each revision of the CAD is measurably better than the last, mechanical and PCB both. I would rather state that plainly than present the work as more finished than it is.”
