OneyedrunkOEM key caps are similar to cherry profile which is what I believe you are familiar with. As you can see in the pictures, the profile goes from 1 where 1 is the tallest cap down to 2,3,4,4 where 4 is the flattest shortest cap. OEM and cherry do still retain a similar profiling (1,2,3,4,4) but the tallest would be more like a 3 in this profile. These are going to be thicker than stock OEM keycaps but they will be taller than the OEM profile. HTH
OneyedrunkThere are 6 different row profiles: R0 through R5. R5 is a flat version for the bottom row. Alternatively there are R4 keycaps for the bottom row - both versions are in many of the kits. R0 is for the Function row, which many smaller boards don't have. I marked up two of Massdrop's photos, and you can read more about the design straight from the designer, Matt3o, at the link.
OneyedrunkThanks for all the replies. I'm aware of keycap profiles and keycap materials, I simply asked what profile it is. I see that it isn't an existing known profile, so my only question is what profile is it most similar to? Cherry? OEM? At least in terms of keycap height..
Thanks
