Printed with adaptive layer height at max quality in black PETG-CF and gave it three coats of a satin clear spray paint for comfort. Not rough on the palms, hopefully will hold up for some time as well.
The author remixed this model.
Just cut a few mm off from each side so it matches up better with my 60% keyboard case. I used a couple of wooden 60% cases from Amazon and the KP Republic Aluminum 60% case for the XD75(pictured).
It is every so slightly wider than the cases(.5-1mm) for alignment purposes, I would have gone .5-1mm narrower but the trackpad is pretty large so I opted for the offset to be larger on the trackpad side.
