These are bespoke, there will be no more, when they're gone, they're gone. I commissioned them to be professionally 3D printed. Robust and sturdy, they raise your Maschine MK3 up in height to be flush with the surface of the Komplete Kontrol MK2 keyboard as the height discrepancy did my head in whilst scoring video games, TV and film with my Maschine MK3 and Komplete Kontrol MK2 (also listed on eBay as I'm changing my workflow with a controller of my own design). This makes the whole thing feel like driving a car with everything where it should be in front of you. They are push-fit over the square pads on the bottom of the Maschine MK3. Wishing you happy music-making.
