Fuck yes

I’ve worked with the Keystone holders and can confirm that those will hold protected cells, at least some I got from nkon.nl

That's a good tip for safety conscious visitors because the webshop is in the same country. Probably a good idea to put it on the event wiki. Is the event still going on?

The last day will be this Tuesday.

Can you please specify the exact type of these cells.

A friend found a 68.8mm cell that fits; the Keystone holder caps out at 68.88mm. Most protected cells are 69.2mm…69.8mm.

I've also written up some more findings. They can be found at https://www.krekr.nl/content/why2025-badge-fire-hazard-addit...

Me fixing a bad micro-USB connector for the n-th time prompted me to write do's and don'ts for mechanical and electrical design of sturdy connectors (not just USB).
