Let's resolve the issue with the Hasselblad lens cap.

The original lens cap features an inner-pinch mechanism.

The original lens cap cannot be used after installing the adapter ring or replacing it with the 10ARTCC steel tip.

So, I redesigned the lens cap.

It connects via the outer bayonet mount, without interfering with the adapter ring or UV filter.

There is 5mm of clearance; any UV filter within 5mm can be fitted directly.

The bottom surface does not require support, whereas the overhangs do. Automatic support generation can be used.
