Geonworks F1 ISO Alps AT102 Plate
Cut from black 1.2mm FR4, this plate is suitable for the F12 versions of the F1. It will work with F12, WK versions of both the 8X and the 8K. Note the 1.5u stepped caps lock, 6.25u space bar, and ISO enter. Any alps keycap sets that use Alps stabilizers and the AT102 layout should work.
