Custom keycap Maya for Air75 V3. Someone show me how to modify the knob?

I just got a Nuphy Air75 v3 with the red switches, and so far it's been a fantastic little keyboard. I was experimenting with some shine-through keycaps, and noticed when I put them on that not all of the keys were a uniform height.

In the picture above, I tried to illustrate this with two different keys in the bottom row. I apologize for the poor photography, I hope the annotations do an OK job indicating what I am seeing a bit more clearly in-person.

When I put the new keycaps on, I noticed that some seemed to be more depressed than others, which was visible when viewing the keyboard's side profile. I thought I had perhaps pushed the caps on too hard (they were a tad tight on the stems). Taking the keys on and off and switching them around produced the same results, so I figured it wasn't that. I swapped back to the OEM keycaps, and same result (pictured). I then thought this was perhaps caused by uneven switches, so I swapped the switches between the keys pictured, and had the same result, so I figured it must be the board itself.

Is this normal? It's not something I've noticed on other keyboards, although admittedly I have not used too many of them and perhaps this is just the first time I am noticing what is otherwise a standard feature. It doesn't really impact the typing experience in a material way, so just trying to figure out if my board is just a bit warped (in which case I may try to exchange) or if this is completely normal.

Thanks for any help from those a bit more experienced!

It's been 1 year since getting this keyboard, so it seemed like a good benchmark for a review! Mechanical keyboards are supposed to last a decade or so, though I don't know how long this one was built to last.

For reference I use this 8+ hours a day for work and gaming

The aluminum body doesn't have any chips, there are a few tiny dings on the edges but it's a soft metal and I travel a lot so I think that's within expectations. Plastic bottom looks great and the sticky feet are still original.

Switches still sound like day 1 except for 1 key that has a ping. I'm not sure if it's the keycap or the switch that's the problem, but it's not a big deal for me so going to leave it until i get new switches or keycaps. I'm a sucker for pitter patter rain sounds and this board + raspberry switches are just right for me.

Battery lasts a couple weeks, it'll probably be good for a while longer. Once this battery cycles out I'm going to remove it and be wired full time, or replace it. I don't see any batteries for sale on nuphy

2.4 works great and so does wired, but Bluetooth has been unreliable since the beginning. I don't use Bluetooth though so that's not a problem.

TLDR

Overall, I'm pretty happy with this board! I'm going to keep it for a while. Typing on it still brings me joy a year later so I think that's good enough for me.

As an aside, I got my brother one too and we removed his battery so he could have his wired full time. If you want a wired one but it's sold out online, you can do this to avoid spicy pillows

So, I recently posted a review of Node75 which I had to return because metalic sound, faulty switches and signal interference, thanks again to people for pointing all of this out and helping me test this.

While I am waiting for Keychron K3 HE and ultra to come out, I decided to trust Nuphy once again and go with the premium option. Hey, maybe my Node75 was a one time thing. Nope, far from that.

With air75 v3, my first experience started with a failed firmware upgrade, and a faulty switch on at least T, F, J switches, I stopped testing further because why would I, I am just gonna return it.

Feel is nice, metalic sound is a lot less because case is structured better it seems, aluminum top is overrated, you forget about that about like an hour, plastic on node75 was just fine.

Firmware is still garbage, as signal interference is also here when you’re playing on 2.4 dongle.

Anyway, as a lot of people pointed out in this thread before me, just don’t buy Nuphy, qc is shit, firmware is shit, support is usually shit too, delivery with Yuntrack and other stuff also doesn’t really help with customer experience.

Anyway, that’s my review, I could’ve gone into more detail about the keyboard itself, but there’s already plenty of that on the internet.

Attached a video of a simple key test showing a faulty T button.

Share your stories down below, let’s save regular people’s wallets together!

Absolutely love the combo - was skeptical about the work louder caps given the cost but definitely worth it!

Got my 1st NuPhy today, and I'm super excited to showoff my mix of the original along with Coast Twilight

Edit: I swapped out half the blush switches with the red ones so they would have the same switch, and the keyboard with the better quality keycaps is audibly better even when I put the same family of keycaps on them. Was the keyboard just in-general built better then? This is incredibly evident in the spacebar. With the same switches and same keycaps, the one on the blush board was SO much less rattley. The one with the lower switch quality‘s gasket mount is also extremely stiff to the point that it feels almost nonexistent. The quality and sound difference between the base board kits themselves under the same conditions is quite noticeable. Is there a huge quality control issue? Or are the different retail versions also built differently?

I know there are two versions of Air V3 keycaps depending on retailer and such, but was it ever mentioned that they were different quality and profile? One of them seems to use a less stable stem, and the spacebar does not have the extra padding. I don’t know I just found it strange, has anyone else experienced this?
