I don't know why this board has the word "Space" in its name because there is very little of it inside. This keyboard was designed by Airpotter of Gray Studio
4mm plate foam cut to the layout of your choosing. Backspace is cut for both 2u and split. Caps is cut for both standard and stepped.
2x 1mm case foam layers cut to accommodate screw-in stabilizers and any extra tall chips on the board. Bottom layer cut to fill every inch of case floor, middle layer cut to reach the vertical LED bar on the side.
Foam pieces came as described, significant improvement in sound after installation. Highly recommend MKUltra's work!
