Cut out of 1.2mm delrin (POM), with reduced leaf springs to account for the flex of POM.
Available in layouts suitable for all versions of the F1.
B Stock options are available in limited quantities for some 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.
