MT3 Keycaps 'rubbing' on each other?

Hey all, I recently got the MT3 Susuwatari on my KBD67 Lite and I came across a weird sound when I press the left side of my Enter key – it turned out that the wiggle of the keycaps actually was so much that it was hitting the side of my \ key (it doesn’t haven’t that sound when the \ key is removed or pressed)

This is strange because I was previously just using my 2048 MT3 keycaps and I didn’t come across this issue. I’ve contacted Drop to see what can be done, but could it possibly be user error with the stabs perhaps (like they’re loose or something?) Has anyone come across this issue before?


Do you have a clear picture of what is happening?

I doubt it could be loose stabs, but try just remounting your keycaps carefully.
Are were the switches properly seated during installation and aren’t crooked?

Do the keycaps sit straight on the switches?


So I actually have had this happen before, and it did appear to be something to do with the stabs, though I never conclusively figured out the exact culprit.

In my case, I think it was the heat-shrink mod I was attempting - it was a little too wide and was causing the stabilized keys to twist a bit as they came down. I was using Durock V2s and MT3 caps and had the issue on the spacebar - took me a minute to realize it was the cap itself hitting an adjacent one.

I also have a KBD56L with KBDFans’ new polycarb stabs - and I will say that while they’re plenty smooth, they do allow a fair bit of rotation. (I don’t think they cause it by themselves, but allow for it if something else is.)

I haven’t had any caps touching on this keeb, but if I nudge them from the side they have enough free play to do so - so some amount of stab tuning may help here - though I’m not versed enough in it (or these specifically) to tell you exactly what needs to be done. Maybe try removing some of the surrounding keycaps so you can get a view of the stabs and see if you can see what/where the forces are pushing the cap this way or that.

There’s a possibility that it’s down to your typing style combined with the play the stabs have; does the key twist no matter where on the surface you press? I’d try messing around with that, too, to see if you can find any patterns there.


Hey! On mobile so short reply: but here’s a vid comparing my two sets of MT3. Double checked the stabs and no issue there. Think it’s def a clearance issue.

Going to send this to Drop support to see what they say — but idk what they can do. In the meantime might try to sand down the edges…?


Yes I think the keys are surprisingly rotate-able with the KBD67 lite which contributes to this - in addition with just the keys being just that slightly bigger perhaps :confused:

I use MT3 on almost everything, and I’ve only really had the issue on that one board - I’m inclined to think it’s something with the stabs, so I’d look at modding them before sanding the caps themselves. I got rid of the issue on the client board I mentioned by switching to different stabs; I didn’t have time then to fully investigate the cause, but swapping the stabs did make it go away.

i also use most of the abs and pbt mt3 sets and i only see this issue with switches with too much wiggle/wobble. havent encountered with stabs

Any suggestions for stabs then? I sanded the bottom edge and it seemed to mitigate it a bit.

I see the “durock v2” in w local seller market - are they any good? They look so similar to the kbd67L one though I’m not sure if I should get them

I wasn’t able to watch your video earlier but now that I have, it looks like the whole cap is sitting closer to the next row up than it should.

It almost seems like something below the cap isn’t seated where it should be, whether it’s the switch or stabs I’m not sure. My KBDfans stabs have play if I purposefully push them that way, but there aren’t any clearance issues like in your video with the three different MT3 sets I’ve used on it. Maybe I could see something from a photo with the key removed.

As for brands, all of them will have some play by design - the cost of tighter tolerances is lower compatibility. Durocks are good, Cherry are good, Zeal and Ink stabs are expensive but good - honestly there’s lots of good stabs. I hear C3 are ok but maybe underwhelming compared to their switches. I have a harder time thinking of bad ones - GMK (poorly) retooled theirs after being a community standard for years and now folks avoid those, but that’s pretty much the only one that comes to mind.

Say all that to say, I wouldn’t worry about the KBDfans stabs themselves - they seem at minimum totally decent - but something does look out-of-whack with your key-striking situation there.


Agreed. This happens to me when one side of the keycap fully seats before the other. It’s usually the Backspace key that’ll wobble (upward) and end up rubbing on the case.

Does your wobble happen if you turn the keycap upside down?

Keycaps ‘rubbing’ on each other?

Gonna need the 6-digit number code for that one, chief…


Heya – yeah I double-checked last night but it’s still creating that clacking sound regardless of the orientation of the Enter key. I also double-checked that the stabs were in properly and that both sides of the key were fully pressed into the stabs.

I think for some reason the Enter key is just a LITTLE bit bigger in my Susuwatari set (compared to me 2048 set) but it’s enough to cause clearance issues.

Drop replied and said that I am going to have to send in the whole set for replacement (can’t just send replacement keys); at this point I think that’s the direction I’m going to go (although it’s a little disappointing since I was so eager to bring my new board to work. Oh well. What’s another couple of weeks I guess.)

I took another short video here hopefully that shows the situation more

If the KBDFans stabs are totally decent (which… I mean I think they are because I never ran into this issue with any of my other keycaps with them) then I think it’s a mix of the stem wobble + slightly larger Enter key.

I’m going to get a replacement from Drop – which is a shame because I like the keys (and I’m worried that the results will be the same), but I think another wait of 2-ish weeks is probably worth it more in the long run.


Well - it sure looks like you’ve done your due diligence to me - stabs look to be set up perfectly. I don’t think even a badly bent wire should do that.

That Enter cap does look to have a twist to it; could be the keycap stem itself is twisted. I love my MT3 sets, but I have had some manufacturing issues with them including one set that had a stem that wasn’t fully formed. (It could also be the switch stem which I have also had happen, but it sounds like the issue doesn’t occur with other sets.)

This really is the main wrinkle with MT3 for me - but at least they do replace the wonky ones until it’s right. My Susuwatari and Cyber sets were fine, but it took more than one try each to get a solid set of BoW and WoB. I hope a fresh set resolves your issues!
