Pull Rod Clip CR10 V3

This is my very first and simple functional design. I needed something to hold my Raspberry Pi on the pull rod of the CR-10 V3. So I quickly designed this clip to prevent my Raspberry Pi from sliding down the pull rod. Additionally, I can easily slide my Raspberry Pi into a desired vertical position. Simple enough.

Of course, you can use the clip for other purposes as well. Well, it's a clip :-D.

Since I'm new to 3D printing, any feedback on how to improve it is greatly appreciated.
