Finding replacement for a single Keycap...an F7 keycap, for Razer BlackWidow Lite

Finally I joined this community...

Hey guys and gals! 

So, let's get to the point, I have the Razer Blackwidow Lite that I use for office and gaming, and recently during my travels, I went real idiotic, and brought it with me, and lost a single keycap (the F7) as I left it in my suitcase.
The keycap is definitely lost, so no hope to just "try and find that and stick it back again"

I've looked around on Reddit and Amazon, and I've pretty much gotten a few of these sites:
https://www.caseking.de/peripherie/eingabegeraete/tastaturen/keycaps
https://www.maxkeyboard.com/black-translucent-cherry-mx-blank-keycap-set-for-esc-w-a-s-d-or-e-s-d-f-and-arrow-keys.html
https://www.amazon.de/-/en/Keycap-Upgrade-Mechanical-Optical-Keyboards/dp/B07ZPRSWPZ?th=1

So, why I haven't contacted the sites I mentioned above, is because
1.) I only need one keycap, why should I get them all? And it's TKL
2.) Even if I did buy the Amazon one, it's unfortunately US/UK Layout, so I'm gonna lose my ÜÖÄ keycaps

3.) I'm also kinda afraid if I buy an individual one, it's gonna have a different height with the others, and just annoys me instead.
4.) MaxKeyboard would allow single ones, but then I have to pay for customs, which would make it a bit annoying, though not really unreasonable.

I've even contacted Razer recently to ask for their support, and found this European site https://www.laptoptaste.de/ which supposedly sells individual keycaps (€3,3 Euros is a lot for a single keycap, but hey, sustainability, yo), and contacted them about my issue.

Anyone else knows where I could get such individual keycaps? Or perhaps an "upgrade" to PBT, but DE-Layout?

Thanks in advance!
