That’s a great project which also shows how hard it is to build a keyboard for today’s ultra thin laptops. As you suggest in your linked post, perhaps the ideal is to be found with the Cherry switch.
Is there a rationale behind the physical format you have chosen - perhaps it is an adaptation of your usual format to the laptop space constraints? I have previously asked if there are any people who would be interested in an Atreus for Framework. Personally, I still think the Atreus would be a better prospect because the format is already (by the standards of such things) widely used and the two sets of columns diverge towards the user to reduce wrist strain. Of course I happen to own one! Nonetheless I have not the wherewithal to actually make it happen and I wish you the best with your project.
