I also have a DTSE9 and it’s been on my keychain for at least 10 years now :D

Recently I have just gotten 2 nvme ssd enclosures and have been very happily using them for the super quick image writes. I just checked if there’s some compact 2230 enclosures and some of those even have keychain attachment points… they definitely are a bit bulky for a keychain but I’d argue they still are an option and will look similar to a keyfob :)

It’s a wobbly affair but it does work and Bambu does offer it as an option with a mounting bracket you can print. I… just put my AMS to the side because my table is already kinda scuffed :D
