FreeCAD design for laser direct imager with a prism, for a technical description see open hardware fast high resolution laser.
The CAD file uses PCBs found here, https://github.com/hstarmans/firestarter.
Design is made using FreeCAD 1.0.0RC2 with the plugins fasteners and KiCad Stepup.
The main file of interest is assembly_compact_new.FCStd, in FreeCAD Files.
Design has been tested and is functional.
There are some videos on YouTube explaining the design in more details.
These are dated.

Creating the rays in FreeCAD is done using pyoptools and the following two libraries.
These libraries are hard to use and require extensive time and python knowledge.
