Arief, you are the one to take the last three pieces.
LiuMing, can you consider doing something like what Particle Wave Technologies did, a cap that can put silica dessicant in it. This way, it not only acts as a cap, but also as a dehumidifier for the internals of the scope.

No problem. I add some pictures here
With these caps, I can put packet silica dessicant in it. I think it will be useful for a lot of people. You don't need to make it exactly the same or just as nice, as long it works.
That will be nice! Perhaps a removable plastic dessicant plug so that we can reuse the dessicant. Unfortunately we cannot microwave the aluminium cap, or you can incorporate it directly into the cap.
Cheers!
