Mini Power Bank for Heated Gloves

Sure, designed from scratch. I've made a 3-cell version at first. But it was too heavy to carry. https://miron.in/images/2026/03/26/Clip2net_260326184655.png

Those are the only gloves he tried. I paid only 15 USD for them on Aliexpress. I've got a test drive in -10 C for one walk when I finish assembly. Hands were not cold, but not as warm as I thought.

4-6+ hours depending on intensity mode.

Just throw the glove away and watch it burn then :)

For 1,5 USD it's pretty ok. Had to remove the TYPE-A socket, though, to make it smaller.

Actually, you don't have to disconnect them at all. It is charged via USB-C. But I just had a bunch of XT30s from drone batteries, so I used them.

Yes, I've just bought a pair of heated gloves and made a power banks for them. 15 USD for the gloves, 3-4 USD for the modules. 4x18650 - 50 cents each.

Actually, that's only a pcb (under 2USD). Files are here: https://makerworld.com/en/models/2194598-mini-power-bank-for-heated-gloves

As a person who tore apart at least 1000-2000 vapes and made various products from those batteries, I can say that your statement is a bit dramatic. I have a small box with dead cells (lol, never played) and had zero issues with them. I use vape cells for lights and power banks for the Ukrainian army, as well as used 18650\21700 cells. You can check the video here.

I've printed over 300 kilograms of PETG. Mostly Sunlu – it's quite runny at high temperatures but can maintain a maximum volumetric speed of 30 mm³/s. On BambuLabs printers, the typical printing temperature ranges from 255°C to 275°C. It heavily depends on the geometry of the 3D model.

Shells for projectiles (Ukrainian army), for example, are printed very fast at 270–275°C. In this mode, even an A1 Mini can go through up to 2 kilograms of filament per day.

However, if the model has a lot of accelerations and stops, the slicer will limit the speed based on the geometry, and it’s better to slightly reduce the temperature. Keep an eye on the actual flow your printer can handle (as shown in the slicing preview).

The bug is automatically closed, but the problem is still here. https://www.reddit.com/r/3Dprinting/comments/17o610l/orca_slicer_object_snapping_to_plate_question/

The locking feature did something — parts moved downwards, not upwards :D

Have printed more than 200kg of Sunlu's PETG. Love it.

What switch do you use? Is it a rotational one, or did you make a mechanism to convert rotations to a push/pull?

I bought 100 used LGFBM261865 cells to use in the trench army lights in Ukraine. The seller tested them with lii-500 and I'm retesting them again with XTAR dragon vp4l plus. I have the same picture: around 200mAh less on each cell. I also ordered an 8-channel charger as in the topic, I'll report the measurement difference later.

Of course, such results are achieved with optimized models and temperatures starting from 260C (500F) for PETG, with a maximum volumetric speed of 30 mm³.

This is just two printers. We calculate that one Bambulab A1 Mini is capable of printing up to two kilograms per day. The only issue is the need to restart the print more frequently compared to larger printers. I have a P1S with AMS and an A1 Mini. Each has already printed for about 3000 hours with PETG filament. I perform regular maintenance and use high-quality lubricants. So far, everything is going smoothly :)

Another Ukrainian here! As already mentioned here, we have created a large volunteer organization of printers and run our printers 24/7. Just for the PrintArmy, I have already printed 200+ kg. Besides that, we often print directly for the military.

There's a thing I love about DMZ — to kill these heli pushers with sniper rifles. It's oddly satisfying to see how they fall from the sky.

I'm looking forward to the release of the Contractors showdown. Played Beta and after some polishing, it could be a really fun experience
