Cut out of 1.2mm white delrin (POM), Only available in the AT101 layout currently, with cutouts for alps style stabilizers.
B Stock options are available in limited quantities. 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.
