Alright, still working on this and wanted to post my progress! I actually made this from scratch in Fusion 360 and after many versions it is coming together. Still needs more work, but the idea is that the lens holders are pretty much a single piece with threads I split in two that has a spot for 6mm lens. Still need to work out the holder for it though.
