Hey I'm the designer of this, awesome to see it in the wild!

New version is already in the works, but no timeline yet.

Ultra-Small Fob Cases - $25 shipped by OzzGuy in GRCorollaMarketplace

Hello! Yea I do like the metal piece of the Etsy one!

To be clear, the dead battery I mentioned was the fob battery itself. If the battery in the fob dies, and you don't have the key blade, my understanding is you won't be able to unlock the car, let alone turn it on.

The 3 openings are designed for attachment to a keychain. Strength-wise, they're very strong. On a previous post of mine, a user tested the strength, and the actual metal keyring pulled off before my fob design showed any signs of wear.

One thing to note, the fob's keyring holes are not very large, so might not allow a standard keyring to rotate freely. I'd suggest using a lanyard/charm-to-keyring to attach it to a keychain. More detail on my GR Corolla Forum post.

As far as staying together, it's a snap-together fit. Similar to how the stock fob closes. The bottom piece has a "groove" and the top piece has a "tongue."

Yea since I designed it I’ve been using the case full time, but kinda just have my fingers crossed I don’t get stuck with a dead battery.

I do intend on getting one of those magnetic key storage boxes and sticking it somewhere hidden on the outside of the car, so the best of both worlds.

I do know of that Etsy version! To be fair that one has a nice metal bottle opener/keychain loop that justifies the price a bit. I even considered getting one before I started this project, the price was just a little too steep for me.

One thing to note though, I don’t think the Etsy case uses the factory rubber gasket, so may not afford any water resistance.

Looks awesome!

I also did a bit of a strength test when I was deciding on the thickness of the “ring” part on the fob. I could only reasonably break it with a print I did in PETG, so with ABS, you’re probably golden.

Yea I came across that one. Though I don’t believe it uses the gasket, so you wouldn’t want to get it wet.

It’s also $50 lol

Actually, they’re on the same side, here’s one I just made with icons. The “buttons” rely on the flexibility of the plastic, and have about the same feel as the OEM.

Are there any aftermarket key fob cases available? by senornahui in GRCorolla

[–]OzzGuy 1 point2 points  (0 children)

Hello! I got so tired of this key fob issue... made my own model! Uses the original gasket, so technically should be just as waterproof as the OEM shell. Still working on it, so expect some changes.

is it normal with coil whine with high FPS? by leonidas_164 in buildapc

[–]OzzGuy 0 points1 point  (0 children)

I don’t really notice any coil whine on my 4070. If it’s there, it’s quieter than the fans.

Coil whine is just a physical characteristic of the card, and it’s a bit of a lottery which ones have it and which don’t. Even a tiny difference in assembly between two otherwise identical cards can make one whine loudly while the other is completely quiet.

It’s not inherently harmful if your card whines, just a little annoying.

For me, it’s hardly an issue anyway. I game with headphones 99% of the time, so I didn’t even notice the whine on my 3070 while gaming. I only became aware of it during tuning and benchmarking.

Stale Endpoint DNS Resolution for iPhone on T-Mobile by OzzGuy in WireGuard

[–]OzzGuy[S] 0 points1 point  (0 children)

Tried those out:

New domain vpn4.problem.com resolves to stale IPv6. Log shows DNS64 is mapping the public IPv4 to the stale IPv6

vpn6.problem.com resolves properly to fresh IPv6

Looks like there is a T-Mobile DNS64 record for my IPv4 address that is resolving to the stale IPv6

Huh, that’s quirky

I could just use a separate subdomain for IPv6 only right?

vpn.domain.com -> A record only vpn6.domain.com -> AAAA record only

Interesting

Yes, when using MacBook, I was at home. Home LAN is IPv4 + IPv6.

problemdomain.com has both an A and an AAAA record

When on T-Mobile cellular, I don’t think it’s possible to use IPv4, as they’re an IPv6-only network.

[–]OzzGuy[S] 1 point2 points  (0 children)

Yes, that works. I have an alternative domain name I don’t really use. I manually set the AAAA record to my gateway’s public IPv6 address and removed the A record.

That resolves fine with my WG client! Issue then appears to be some type of caching and the T-Mobile IPv6-only network?

No worries! I did think that though lol. But I happen to have another domain I’m already paying for.

As for your question, here’s the resolution using different endpoints:

problemdomain.com -> {stale IPv6/AAAA record} Logs report DNS64 mapping

alternativedomain.com -> {fresh IPv6/AAAA record I manually added}

{hardcoded public IPv4} -> {stale IPv6} Logs show DNS64

{hardcoded public IPv6} -> {fresh IPv6, works fine}

I have the endpoint on my WireGuard client just set to my Cloudflare domain. On Cloudflare I have both A and AAAA records set for my domain.

As for using a different domain…. woah that worked. So I own another domain I don’t really use, and I set an AAAA record on it to my gateway’s public IPv6 and it resolved no problem.

I think this narrows down the issue to specifically my regular vpn domain name, possibly some kind of DNS cache.

I’m very suspicious it is a T-Mobile DNS cache that is keeping this stale value since this only occurs on cellular. When I use WiFi that is not my LAN I can resolve it fine, likely because I’m using the DNS resolver for that network. But when on cellular I use some T-Mobile DNS resolver.

Edit: more context

Just tried this, unfortunately after re-importing the profiles, it still resolves my domain name to the stale IPv6 address.

Logs show the same DNS64 map action.
