> It is absolutely possible to do this, but the resulting battery pack won't be nearly as solid as even the third party packs that are available. With the amount of time required to fiddle with the connection paperclip and winding the temperature sensor leads around a tiny plastic tab it is probably not worth it to print your batteries.
Very common practice in music gear industry, unfortunately. I've recently bit the bullet and bought MyVolts Step Up for $20, it is literally a PD trigger worth maybe 50 cents plus a plug.
The author didn't go far enough, should have ripped out the battery holder, installed a single lifepo4 or lipo, added a USB-C charging/protection board and a low quiescent current LDO to simulate 2.7V a couple of freshly charged nimh's puts out.
Author here, the best solution I think would be just ripping the temperature sensor from the battery pack and soldering it to the contact in the microphone instead, then you can just pop in regular rechargable batteries and it'll work. No need to add lipos to this.
At least in the newest headset Sennheiser announced user replaceable battery, without announcing the price or if it is a standard format that you can buy everywhere or a very pricey gold-pressed latinum custom audiophile one.
This is a common arrangement. The replaceable batteries in phones also usually have 3 or 4 terminals for a thermistor.
I suspect many of those who have 3D printers may also have enough scraps of plastic lying around to be able to make something like this from; a few sheets cut and solvent-welded together would likely be stronger.

At 8 mics and 6 in-ear packs you can get a lot of alkalines.

It is ridiculous how many different battery packs canon makes.

My Sennheiser RS 180 still works with normal rechargeable AAA batteries (charging on the official station).
Yet another case where the newer models are just worse.
