I made this revision of the original design. https://makerworld.com/en/models/14347?designId=14347#profileId-51646

I found this project very useful but in my opinion too large in size. I've been using it for some time and I decided to redo the model from scratch by slightly changing the measurements making it more precise so as not to have problems with the ball coming out during the padel game. I perfected the shape by rounding the corners so as not to bother or damage the balls when they are stored

Continuing to use this object I arrived at my second version, solving the problem of the edges which can be annoying during the game.
