Fishing Magnet Cover

I designed a cover for my 2" fishing magnet so it wouldn't stick to anything on the way to the lake. It has 0.2mm tolerance on the diameter so it's a firm-but-not-stuck friction fit (on my printer).

This is the magnet I'm covering:

There's also a hole on the bottom for a 6mm diameter 2mm thick neodymium magnet, but in my case it is totally unnecessary for holding the cover on.
