3D-printable battery covers and battery packs?

[adumont]

Hi, I'm interested in printing the Battery N cells cover, but I can't find the dual coils springs anywhere (all the previous references in this thread are no longer working). Any reference? I'm in Spain, so I'd rather prefer to find them in Europe or even better Aliexpress if available, but if anyone has a good name or reference, it would help finding them. Thanks in advance.
