Cut from premium grade EVA foam, these foam mats are designed to sit between your top plate and PCB. They are 4mm thick and with a standard 1.5mm plate, they will compress about 10% to create a single composite sandwich.
Guaranteed to reduce rattles, vibrations and dampen the sound of keystrokes. It makes bad switches sound good and fake switches sound real. It will increase hair growth in places you want it and eliminate hair where you don't. If you don't feel 10 feet tall while typing on a keyboard with this foam inside, why, you're the one who's defective and should be returned for your own money back!
No sharks were harmed in the making of these plates.
** Important Information Regarding Foam **
Thickness on this current batch of foam is 4.2mm to 4.5mm, so fit will be a little tighter than normal. It still works great, it just requires a little extra pressure while soldering your switches in place.
I bought this knowingly my non-standard 60% keyboard wouldn't be fitting correctly. Just took an exact-O blade and cut off where my switches needed to fit and there was little to no little bits or mess. I would definitely recommend this to any 60% board being built.
60% ANSI Plate Foam
a 2mm option would be great. 4mm causes issues with hotswap pcbs
Added a good amount of solidness and heft to the thock of an older 60% build I had around that previously suffered from a bit too much resonance. Very pleased with my initial experience with this dampening foam. A couple minor things were a bit weird, first the stabilizer cutouts had to be wrapped around my stabs slightly awkwardly, and second there were a couple of places in the foam where it was cut very thin, and that caused the foam to be damaged more easily. Also it was kinda hard to remove the foam from its Ziploc without damaging it.
All these minor things aside, this is absolutely still a 5 star review from me. I'd highly recommend getting some of these. Breathed new life into an old daily driver for me.
I love making my keyboards feel more solid and prefer the deeper "thock" tones, so I'm not new to adding materials to my keyboards to achieve these effects. I usually use thick tool shelf liner that I manually cut and add into the case, but this doesn't work with every build depending on the clearance of the case. I have considered cutting liner to place between the PCB and plate, but I wasn't able to do this consistently or effectively, and so I took immediate interest in MK Ultra's foam when I happened to see it mentioned in a Discord channel I frequent. I purchased a few of these foam pieces to experiment and am happy to say that I was blown away by the quality and feel of this foam! I use the 60% ANSI foam for my Instant60 PCB and Weaven build (see link here for reference: https://www.instagram.com/p/BzTUDkkHONV/?utm_source=ig_web_copy_link), and I love the stability and sound dampening that the foam provides. It fits perfectly, is easy to install and use, and I couldn't be any happier with the results! I like to compare sound tests of my builds, so I was able to record a before and after sound test, and I could definitely tell that the foam helps my build sound more solid and "thocky" (see my YouTube here for reference: https://www.youtube.com/watch?v=dDXbFOG2-nI).
I messaged MK Ultra to thank him for the innovative idea and quality (as well as affordably-priced) foam he provides, and we ended up having several pleasant exchanges. He seems to be very open to new ideas and custom projects, and I love his passion for his work. Due to how genuine and humble he is about his small business, I would gladly continue to support him and buy more foam! Bonus for the quality foam for my builds. I'm a happy customer and will definitely be returning for more foam!
