I have little doubt that there will be a robust market for these among the Leica faithful. If they do prove popular, maybe there would be a market for these in a variety of lens mounts for $9.99 on eBay. Of course, they would not have an official brand logo on top.
If you just need these for storage, I saw this morning at the grocery store some RubberMaid storage containers for $3.99 for a set of four. Each one is just the right size to hold one of my lenses, except for my 80-200 zoom. You could write the lens name on the side with a Sharpie, and they stack. Of course they don't have a red dot, but they do have red tops, which is pretty close. Your choice: $280 vs $3.99 for a set of four. I don't really need them. I have all my lenses in one plastic container on the shelf. That works pretty well for me.
