Good news, everyone: The o-rings arrived today, the floating mount style works … kind of?
There’s three circumstances that should be addressed.
- The modified Klippe R4 PC is slightly warped (hence I got a replacement back in the days — thanks Mekanisk — and therefore I was quite up to modifying the case this irreversibly the first place).
-
Also my PCB is slightly bent in a U-like form, which is somewhat unfortunate, especially because …
-
I’m using screw-in stabilisers which have, well, screws on the bottom of the PCB, basically at the peak of the bent PCB.
To workaround these issues, I added in total four tiny silicon bumps to the case; I mean, at least they’re slilicon and not polycarbonate, I guess?
The o-ring I ended up using is 175 mm inner diameter × 4 mm thick NBR 70 …
At the screw-in stabilizers, I carefully pushed down the o-ring with some flat thing, in my case the back of some tweezers.
I still think that with all of the parts maybe not warped, and probably using clip-in stabilizers, the mount style might work a little better. The typing feel, at least, is great, and also the sound profile was never as pleasing as it is now (even though we’re talking about nuances here). Compared to before modding, I’m not using any foam, neoprene, or silicone anymore … I though about adding 1–2 mm of liquid silicon to the case instead of the four silicon bumps; might give that a try, maybe.
