This has happened before. Be careful what you wish for, specially with e-switch lights. Much easier for PCB mounted switches and standard size drivers.
The SC31B is a much better candidate, but on a deal it's so cheap, not sure a host version is worth it:
Running Anduril now:
Actually I take that back. I see the price at $5.49 - wow! Give me a SC31B host, preferably with the switch PCB for under $10 and I'd buy a bunch!
And
You’re just salty cause you broke the plastic pin.
Not only. Sofirn sells this flashlight guaranteeing IP68 protection (The waterproof level: in accordance with IP68 (Ingress Protection 68 - withstands dust, dirt and sand, resistant to submersion up to a maximum depth of 1.5 m underwater for up to 30 minutes)).
I doubt that it will withstand even IPx3.
If Sofirn intends to sell a completely dismantled flashlight, it should be prepared that the plastic part that is machine pressed can be damaged if folded in another way.
Pretty sure they sell the complete flashlight garanteeing IP protection, not the host which you (as you did) could screw up. Then again, I’m pretty sure they thought about that… isn’t there some sort of gasket to put in between? When I took apart mine (sp31) I remember there was something stopping water ingress.
If they had to be prepared for everything they couldn’t sell the host at all. The buyer is expected to have the nessasary tools and skills to assemble it… that’s the point of buying a host to play around with. Selling one to a person that, for example, can’t solder would be a waste of time.
Then again, It is good to know that it would be easier to have that part preassembled. But it’s kind of annoying if you list them as PROBLEMS when some are obviously to be expected (the driver thickness).
For the price of that host… Can’t really complain. $5.49…
Reminds me a lot of the old Thorfire I got “free for review” that I couldn’t stand. That entire style of switch is a hard pass for me. Completely destroys the ability to mod. Wouldn’t want to assemble, either, for reasons it seems you discovered…
Yeh, gone are the good ol’ days of removable pills, simple tailswitches, interchangeable parts, and easy modding. I still got an assload of drivers, LEDs, etc., for modding the old-timers, but newer lights are nigh impossible to mod simply. Gotta drill this, grind that, epoxy-fill something else… nah.
I switched from even buying C8s, S2+es, etc., just to mod, to just getting off-the-rack lights and leaving them bone-stock. Also cut down my expenses from buying “host” lights on a whim, to only those that I can live with unmodded.
The SC31 Pro sst-40 Anduril is a nice surprise. I didn’t see any dev discussion anywhere on this but just ordered one.
Wow, they manufactured my SC31B modded light! 
Any chance you did a write up? I’m assuming the aux led was able to be controlled by Anduril?
I guess the sp10s Anduril is taking so long, this was next best upgrade.
Well go figure! I just designed and ordered a Anduril-compatible FET+1 driver for the SC31B today. 
Though all is not lost, I made it (1) to retrofit lights I already have and (2) to serve as a testing host for TinyAVR 1-Series testing.
Actually, I wonder if anyone would fancy a light-weight 14500/AA headlamp. Vapcell offered some high capacity 14500 cells, if I recall correctly. Certainly, this would not be a high performance headlamp but something with around 300 lumens. Sofirn's SP31 V2.0 uses a rather good CC driver but it may not work with AA batteries. I am just thinking/dreaming...
I’d get one. I use my Manker E03 often and wouldn’t say no to another AA headlamp.
I would be very interested is this!
looks very intresting, might end up replacing my Skilhunt H03 as car/emergency head lamp
A 300 lumen headlamp with Anduril? Why Anduril?
Headlamps should be super basic in operation. Sofirn need to target a larger audience than just us lot to make it worth while.
I sell to the average consumer in New Zealand and they hate Anduril as there’s way too much features and muggle mode has limited brightness which makes it useless to most who buy the headlamp/flashlight for the advertised lumens
The SP40 UI is ok for a headlamp. Just add direct to low. For a more versatile light, add moon. Still, Anduril would work, too. And better.
I'm torn if I should fully agree or disagree with you. Yes, a super-simple UI would fit best to an AA/14500 headlamp. One of these UIs that one can operate even under distress. One of these UIs that can still be used with closed eyes, with the headlamp mounted to your forehead. I talked to Barry (Sofirn) some minutes ago. He's totally in for an AA/14500 headlamp, using a simple UI.
Now, then there are those flash-o-maniacs here, the ones who really want to "fully loaded" version with all the nice benefits that Andúril can provide. Again, I agree that Andúril might be overstraining some customers, leading to a higher return rate for vendors, leading to many questions from customers and so on and so on... But still, there's a market (niche) for lights with a complex UI. Having the best of both worlds is hard to achieve. AFAIK, TK is about to unlock some features of the Muggle mode in Andúril 2.0, so maybe there's some silver lining on the horizon.
Not sure if/where I posted it, but I can't upload pics right now - PhotoBucket trashed my account or something. Ever since their recent update, my uploading has been flaky at best.
It was a simple driver swap mod, using a DEL 85 FET+1 driver running Anduril with AUX LED support for the switch LED.
Ooops, here it is: https://budgetlightforum.com/t/-/54158/1289
The code is already working. Mostly just doing more testing and documentation now.
It uses a simple UI by default, but the extra features can be unlocked by people who want them. So, straight out of the box, it gives people access to on/off, up/down, lockout, battery check, and factory reset. If they want more, there’s a way to unlock it for full access to all the extra modes and features.
