Geonworks F1-8X Alps Plate
Cut out of 1.2mm white delrin (POM), with reduced leaf springs to account for the flex of POM. To reduce flex and firm up typing feel, soft foam underneath the pcb can be used to taste.
Available in 3 layouts currently -- AT101, Tai Hao, and DCS (also compatible with Tai Hao and Costar Stabs).
B Stock options are available in limited quantities for all variants. These B Stock plates have kerf adjustments that are slightly too large, causing a significant portion of the switch holes to be .1 or .2 mm too small. The plates are perfectly usable with a little work -- any switch holes that are too tight can be shaved quickly into a usable size. A fraction of a mm of material will just need to be shaved from the top and bottom of the hole with a knife.
