Guitar Helper Clip

I like to play guitar in standing position, but I don't like a guitar strap on my guitar.

So I came up with the idea of clipping a tiny platform to my belt, where my guitar can rest on.
Later I finetuned the model and created an option to add a rubber top for protection and grip.

Feel free to share how you use this clip and if you have suggestions for improvements.

I printed the clip in PETG (But PLA will work just as fine) and the rubber top is printed in TPU semi flex.
