Extract STL from .form

@DamienB built a tool that could extract STL files out of old .form files. Unfortunately it no longer works on files save by the latest version of Preform.

Has anyone else figured out how to do this? What did Formlabs change to complicate it (e.g. is it encrypting/obfuscating the STL’s or something?)

It’s kinda logical for them to lock the format, since PreForm is free to download anybody could use their orienting/supporting/packing tech to then use with other hardware.

That being said, I would definitely like to be able to play with the STLs as well…
