Modeling an F key mechanism

[DMA]

Turns out, using MX stabilizers is quite tricky with buckling spring mechanisms: barrel top is 0.6mm above the top plate and all the dust and bread crumbs will go straight under the flipper.

So one either needs to severely redesign key travel limiter or add dust caps to the stems.
Added dust caps today. Not sure they warp when molded - I want to have a flat side so that LED can be added, and post-molding shrinking of the assymmetric part can be problematic.. Will think about travel limiter redesign.
