Planck PE foam
Cross-linked PE foam for the Planck ortholinear keyboard by OLKB.
Separate versions for no spacekey, one middle spacekey, and two spacekey layouts.
Note 1: Does not support rotary encoders. You will have to modify the foam if you wish to use one (or more).
Note 2: We STRONGLY suggest that you do not use 4mm plate foam with PE foam. You have been warned.
A special thanks to mcheddadi. Without his research and contributions, we never would have been able to offer this product to the community.
