Hello,
no, I don't have any specific plans, at least not in terms of detailed models. Lens mounts like are available from Thorlabs etc. can be downloaded from there in a step format and converted to be used in Blender. Their geometry is usually also quite specific, so generating in a functional way, as is a point of OptiCore, doesn't make so much sense as far as I see it.

Of course, if someone posts a specific request, with some explanation of a parametric design where this makes sense, then I would consider adding that.

An example of what I last did implement (but again no specifiicx further plans at the moment) is the "lens housing" option that now exists on the import-from-zemax function. However, this is just a simple, functional baffle for quick rendering, and not intended as a proper mechanical model.
