Will any colourless turpentine do fine or should I seek specifically white spirit?
there is no way to be sure with those inexpensive brands, it is always a lotto. but in this particular case, it is certainty 99,9% you will get new holder, they seem to stop making first gen holders
i stopped using all my oem holders and bands, i print my own, and i use 35-40mm bands. for d10-25 as well as zebralight and skilhunt.
if you can print, you can find stl in this thread, [Review] 77 Outdoors D25 Headlamp (18650) and it is tested and it works great, just print it on the side,
i also designed my own holder for d10-25, as well as zl h600. i have no way to post stl here, not i have acct at stl hosting sites, but if interested pm me i’ll email you stl.
btw, you can heat up 2nd gen holders grips and bend them in tiny bit, and it will hold just as good as 1st, i tried it and it worked great, using a construction heat gun, but i set it too high, and edges started bubbling, but it still held the light firm.
In my experience white spirit helped me to open the bezels of Thorfire TA13 and Sofirn SF30A flashlights. Like alcohol, its pervasive.
Turpentine should also work, it helped me dissolving a massive bonding layer of glue from a battery pack in the case of a DIY power bank I once built.
Depending on how tight and how much glue a nice bunch of hours for it to work, or maybe a day or two, may be required.
What effect would white spirit have on a driver? Some drivers are glued and a real pain to get out.
JasonWW I doubt white spirit will have any detrimental effect on a driver board. You can also try with gas, after all white spirit is similar to gas but with 0 octane rating. Just don't dump that gas into your car's tank afterwards… :-D
Do you mean that gen 1 is good and gen 2 is bad?
Are all companies that manufacture these lights using the same holders?
I’ve wanted to try your holder for some time already. My employer purchased a 3D printer a week ago and I hope I’ll be able to use it. Anyway, I know that I like the current holder and I don’t yet know if I like yours - and I would surely want to order something that works.
Yes, 1st gen had thicker grips and gripped a lot better. it looks like every light of those types no matter the brand come with identical holders
the stl in the link i posted isn’t mine, it was designed by gchart. mine are for wider bands. they are larger and thicker, i’ll post pics when i get home.
molded plastic is much stronger than printed, (i have not tried polycarbonate, or nylon, or carbon fiber filled filament, they supposed to be stronger, but my printer can’t handle them) i have tested several designs, printed in different positions, from different materials, (petg, abs) , as well as oem. i bend them to the point of braking, that is why i designed mine to be thicker, and larger then oem, Gchart’s design is strong enough to last a long time, if printed on the side, (layer orientation matters a lot, as far as strength) uses original rubber strap. he also designed one for wider strap.
Simply amazing
BTW I wonder when will we see a Type C variant…
Are you waiting for… Christmas? :-D

Yeah, I know I can buy converters. But I hate this hack. I guess I’m waiting for the year 2020…and in these lights it failed to arrive so far.
Fact is it is better to be flexible. So, if you stopped buying USB A to micro-B cables you are better buying converters. After all, the USB micro-B connector is smaller (takes up less space), cheaper and perfectly adequate for (at least) up to 12 - 18 W of power.
I also hear that cassette tapes are adequate for playing music. 6 volt positive chassis is an adequate electrical system for automobiles. The bow and arrow make an adequate weapon. Horse and buggy make for adequate transportation.
Just because something is adequate doesn’t mean progress should stop.
A couple of reasons why Micro USB will be around for a while. It’s less complicated than USB C. The connector is also simpler (fewer pinouts). Therefore it’s cheaper (how much more I don’t know) to make and integrate into devices. Ever wonder why cheaper devices still have it? It’s good for charging. Here’s why I don’t like it…the connectors are flimsy by design. The USB C connector is more robust. I’ve had perfectly good devices go in the bin because the USB micro connector failed or just wore out and couldn’t be repaired (can’t charge the device). USB C can access higher USB speeds/bandwidths than Micro. Will it get replaced eventually? You can guarantee it. Will they keep developing/improving it? Probably not, but it will be around for a while.
Respectfully… I feel like it’s still around largely because it’s what the manufacturers know and are accustomed to using.
As far as being more complex… sorta. There are more pins that can be connected, true. Like MicroUSB, though, you only need to connect two pins (power and ground) in order to charge a device… so long as you’re using an A-to-C cable and not a C-to-C cable. In that sense, the jacks are practically a drop-in replacement.
But in order to handle C-to-C cables, you do need two extremely cheap resistors (like $0.0001 or less in bulk) in the device attached to a couple of the pins so that it gets properly identified as the receiving end. Is it an extra measure that needs to be taken? Sure. Is it really that much more expensive or complicated? Naw.
Now if you want to open up the can of worms that is QC2 vs QC3 vs PD, etc… ugh. But there’s no reason to in a flashlight as long as you don’t need a high charge current/voltage.
:laughing: :partying_face:

Now don’t go raggin’ on Horse and Buggy man. 
When the Electromagnetic KaaPows drop, the Horses will still operate.
Matter of fact the Amish have been preppers since before that term was even mainstream.
Organic food?, yep, Solar? Been there done that. Generators? Oh hell yeah, big diesel jobs.
They dig LED’s though, now their buggy batteries last for months without recharge instead of once/twice a week.
Some of the newer buggies can use Dewalt tool batts to run the lights, usually 2 of them in parallel.
They are much more tech savvy then most people realize and also understand all types of medical procedures and the equivalent natural options available.
One of my neighbors traveled to Germany for a back operation that the doctors here would not do because of liability and even after the airfare and lodging it still cost less and worked like magic.
Sorry for the off topic.
Carry on!
Cassette tape player motors consume far more energy than an MP3 player. Just sayin’. 
By the way, out of my above posted adapters in #234 the ones from links 2 & 3 do not work for data transmission, tried them to connect an EBD-M05 battery tester to PC via type-C cable and failure. So beware.
