Where can I get a replacement cap for my Apple Pencil?

I'm confused. Your signature suggests you have iPad 11 Pro. You're asking about a first generation Apple Pencil, which isn't compatible with an 11" iPad Pro.

You may be able to get replacement parts at your local Apple Store. You can also check to see if Amazon has anything which might work.

That is a 2nd generation iPad Pro 12.9" released in 2017. The first generation Apple Pencil is the right pencil for your iPad. My above suggestions for trying to get parts are the best options available to you.
