these are for the v3 base plate https://github.com/Bastardkb/Skeletyl/tree/main/archive/V3
they have the honeycomb filled in to give better adhesion for magsafe sticker mounts
there is a version that also adds 4-5mm of spacer to the plate to accommodate if you have installed headers on the bottom of the pcb for the ribbon cables.
