Pen Cap for Lenovo Digital Pen 2 / ActivePen

Pen cap to protect the plastic tip from drops.

Designed specifically for the Lenovo "Digital Pen 2", though there are multiple versions by that same name, it should work for all of them and many other 9.5mm diameter pens.  Mine measures to about 9.55mm with calipers.

Credit where credit is due:
I saw this one for the apple pencil and thought I'd put in the absolute minimum effort to make an equivalent for the stylus I have.
Theirs is a lot nicer looking; the round body of the lenovo pen doesn't lend itself well to a stylized cap.
