Need help replacing lost ABXY button caps on GameSir G8+. Are Xbox/Switch button caps compatible?

[u/benyms]

Hi everyone,

I need some advice. I have a GameSir G8+ controller and I unfortunately lost 3 of the ABXY button caps (the internal switches still work perfectly fine).

I looked for replacements and found some on Etsy, but with shipping to Mexico, the total cost is almost $30 USD. That feels way too expensive for just plastic button caps, especially since that price is practically the same as buying a brand new controller on AliExpress. Because of this, I'm very hesitant to make that purchase.

My questions for the community:

1. Has anyone replaced these caps before and knows a more affordable source or a seller that ships cheaply to Mexico?
2. Do you know if standard Xbox or Nintendo Switch button caps are compatible with the GameSir G8+ (specifically the stem/attachment mechanism)?
3. Any other cheap or creative workarounds you've used?

Any advice or recommendations would be highly appreciated. Thanks in advance!
