This combo kit includes 4mm plate foam and 2mm case foam with hotswap cutouts.
Installation requires taking the board apart, putting the plate foam inside, slipping the PCB back into place GENTLY, putting the case foam on the PCB, putting the 'acrylic' (plastic) diffuser back into place, press all of the plastic plugs in tightly to hold everything together and then screw the top half to the bottom half.
These foams are designed to fit the ALT LOW PROFILE - a keyboard designed and produced by DROP (previously Massdrop).
Small note: Drop has recently added a brace to the ALT. To account for this divider there is a scored a line in the foam for you to cut along if your ALT happens to have this divider.
Just got my kit today and it's amazing!!! This kit will fit the high profile ALT if you trim the little wings on the sides of the piece that sits inside the light diffuser. After putting it all back together with my lubed and filmed Zilents, it's even quieter than it was with just the switches. It makes the board feel even more solid than it already did! A must buy for sure!
This foam was just what I wanted to improve the sound of my new Drop Alt. The sound is now much more bassy and thocky, which I really enjoy.
Installation was pretty easy. I have the new version of the case, which required I separate the foam along the grooves. I used a fairly dull exacto knife to make it easier to separate since tearing it left some jagged edges. I recommend you get one that's nice and sharp!
My one minor gripe with this foam was the bottom-most layer required I cut it so it wouldn't sit on top of the led diffuser and be too bulky to close the case. This wasn't too difficult for me and my not so sharp knife, but it would have been nice if the foam just fit, right out of the box.
While I was installing the foam, which required removing all the switches and dismantling the case, I took the opportunity to also clip and bandaid mod the stabilizers (which I'd like to replace once stabs come back in stock and I can get my hands on some).
I've since lubed my switches (stock Halo Trues) which did improve the sound and feel, but not nearly as much as this foam.
I suppose you could always find some kind of foam material elsewhere and cut it down to the right size as an alternative to this foam, but I didn't want to mess with that so this foam was a great option for me!
If you're thinking about getting this foam and it's in stock, I definitely recommend it! If it's not in stock, sign up for updates so you can snag it when it is.
After cutting it up a bit so it fits in the newer low-profile case, it works an sounds perfect, no ping at all!
Massdrop Alt Low Profile Foam Combo
The foam fits and does what it says it will. It is well made and easy to use. I received mine in about a week.
I purchased the case foam for my drop alt high profile and it was almost a perfect fit. I did have to trim the edges a bit since I have the high profile version of the drop alt. I will be purchasing again from this company!
