Hiking stick bagpack hooks

Since my hiking sticks are not foldable, I decided to design small hooks to be able to mount them at my backpack. I designed tow different versions. One with a hole and one with a hook. The inner diameter of both parts is 16mm.

Update: I just added a version for two hiking sticks
For those files the following diameter are used.
The inner diameter of the part with hook is 15mm and the inner diameter of the part with hole is 16mm.
