I have made an assembly design of the laser scanner in Freecad using the new assembly 4 workbench.

I am really happy with this workbench. It really helps with the open-hardware concept of the project; without these tools it would not be possible to give other people the ease of use to adapt and add their modifications.  Companies like Prusa Research are open source but not open-hardware as they don't provide access to the assembly drawings. They might do that in the future with these new tools.
