Case and plate foam for the Glorious GMMK Pro

3mm OR 4mm plate foam 

2mm case foam


How do I choose between 3mm and 4mm? 

As many of you are aware, the GMMK Pro's gasket mount is super compressed so the board has a VERY firm typing feel.  Normally, for a firm board like this where standoffs between PCB and plate are basically mandatory, I'd suggest using 4mm plate foam to suppress plate ping. 

However, I tried something I'll call semi-float mounting the board:  I removed the bottom gaskets that attached to the case and removed the two internal standoffs, and let the PCB "float" on the case foam.  I left the two side gaskets on the bottom, which support the PCB, and all the top gaskets. The case foam keeps enough upward pressure on the PCB/plate assembly that the points at which the plate is gasket mounted actually do NOT touch the bottom of the gasket area (without the gasket) under normal typing conditions and, at least in my opinion, leads to a less harsh typing experience.  Doing this with 3mm, in my experience, adds flex back to the board.  Yes, you can also float mount with 4mm foam, if you so choose.  

Also, if you are using the polycarbonate plate or one of the AVXWorks FR4 plates, we similarly suggest using the 3mm version.
