Gift ideas

Hey dudes. I’ve recently gotten into outdoors rock climbing, and I wanted to get/make a gift for this guy who’s been teaching me everything. He’s been taking so much time just to teach me, and it means a lot to me. I’d like to show my appreciation
somehow. He’s really creative and does a lot of art, a paramedic/volunteer firefighter, and is really passionate about what he does. I’ve recently gotten into sculpting, so I think it could be cool to make something, but I have no ideas. Doesn’t have to be explicitly climbing related, just something cool.
Any advice/ideas would be greatly appreciated. :)
