Please consider providing fully-assembled CAD of the illumination arm (incl. mounts/posts) for both CYL and Powell configurations

Hi Altair team,
Thank you for sharing Altair-LSFM and for keeping the project open and builder-friendly.

I’m planning to build an Altair-style illumination arm, but I (and many potential builders) don’t have access to Zemax/OpticStudio. While the perforated/custom baseplate design greatly reduces alignment burden, without Zemax it’s still difficult to reliably reconstruct the exact optomechanical geometry (lens positions and the offsets introduced by specific mounts/posts/adapters) and then generate a correct baseplate CAD for our own available hardware.

Request
Could you consider releasing fully-assembled CAD (not only custom parts) for the illumination arm, including:

All optical elements placed in their optimized positions

The corresponding optomechanics: lens mounts, posts, post holders, adapters, folding mirror mount, galvo mount, aperture mount, etc.

A reference coordinate system (origin + axes, beam height) and any key dimensions/constraints

Exported neutral formats (e.g., STEP) so users can edit in different CAD packages

Ideally, two complete assemblies:

Cylindrical-lens (CYL) configuration

Powell-lens configuration

Why this helps
With an assembled “ground truth” CAD, builders who do have CAD-editing capability can swap in alternative mounts/posts they already have (or locally available equivalents), update the hole pattern/dowel pin positions accordingly, and still stay close to the original optimized geometry—without needing Zemax.

If these assemblies already exist somewhere in the repo (or in supplementary files), could you point me to the exact path/links?

Thanks again for making Altair accessible to the broader community!
