Made of card stock and packing tape, the case was made in 2024 and still holding up great.

Measured to hold a Clipper lighter and cigs made with 70mm long papers.

Holds roughly 8 cigs with the Clipper, 12 without the lighter. Lid closes and holds with magnets.

DIY is basically the same size as a regular cig box, but much thicker and sturdier. Two years in the pocket, in a backpack, in the rain, etc., not a single crushed/ripped cig. A regular pack never lasts that long, and actually a small impact on my backpack crushed like 4 cigs which is why I made my own.

Last pic is the template I made. Fold on dotted, cut on solid. The only thing I forgot in the template was cutting out the window to grab cigs, but that's an easy process once mostly assembled.

Really simple template that you can create yourself in a program like GIMP. Just measure a Bic and some cigs, you got your width and height. Everything other dimension is based on that, either same or half. Lid flap would be however long you want. Really simple construction.

I didn't see many results in this sub about this headlamp (Nitecore HA11 UHE version), but /r/flashlights suggested this might work for what I wanted (the thread):

• Lightweight

• USB charging with replaceable battery

• Lower output modes (don't need high lumens, prefer longer runtime)

• Red light modes

HA11 fits all those needs except USB-C charging, but there are 14500 that have USB port charging. Apparently, these types of batteries are actually pretty decent these days. There are "AA" with USB port charging as well, but run at lower voltages. Lithium Primaries (non-rechargeable) are the lightest.

Weights of my own cells:

Battery Type	Weight (g)
Alkaline (included)	22.99
NiMH (Eneloop)	26.22
NiMH (LADDA/Eneloop Pro rewrap)	30.24
Lithium Primary (Energizer)	14.78
Li ion (Nitecore NL1411R)	20.74

The Nitecore NL1411R has USB-C, 3.6V 1100 mAh. Skilhunt BL-113C is a USB-C 3.6V 1300 mAh 14500 cell, but they only ship batteries with flashlights, not standalone.

Attachment	Weight (g)
Stock Headband	12.60
DIY Headband	5.43
Clip	5.25

The DIY headband is 1/8" shock cord and the cord lock is from Michael's (0.75g). Here's how it's attached ONE and TWO. Here's a video of me shaking it a lot: https://streamable.com/td1zbx (muted audio to spare you clacking sounds).

I could go under 50g if I ditch the cord lock and got 1/16" shock cord. Attachment would be a little different though. The headband frame has holes in it like the old NU25/NU20 Classic, so you'd put the cord through those holes. Could then chop off the parts of the frame that hold the actual headband.

Compared to Flextail Helio 600z (63g), which did appear on this sub, this is a better alternative IMO.

• AA is ubiquitous and findable everywhere, CR123A or 16340 is not. If shit really really really hits the fan, I can likely find a detour to a gas station on a bikepacking/touring trip.

• Lower lumen setting means longer runtime, even if the watt-hour of the cells are similar unless the Flextail steps down A LOT on the 100 lumen mode, which would be bad.

• I'm sure you can shave some weight from the Flextail headband, but from my estimate, it'd be max 8g (similar to NU20/25 headband mods) while the HA11 is lighter with my heavier DIY headband.

• HA11 come with a clip, so if you prefer your light on the waist or shoulder strap or even hat, you can do that. The clip isn't that light at 5.25g, but you can drill some holes or something. Flextail does not have a clip option.

• My biggest issue is that the water resistance on the HA11 seems a little sus, Flextail's seems better.

I am not advocating this as a replacement for the Nitecore NU20 Classic, but if you despise built-in batteries then this might be the best option out there, especially if you can get your hands on Skilhunt's BL-113C 14500 batteries.
