I get a lot of Stardust corrupted in April.
Since then, I have many times repeated assembly and disassembly.
The following is how I was easy to do.
1. Remove a metal cone and a silicon cap.
(At this time, can dry burn.)
2. Put a small screw that plate diameter about 6.5mm on the center tube.
3. Pressed against a bolt to the screw.
4. Push with a clamp.
