Solid Mobile Goal CAD

I am making some mobile goals from cardboard and in need of a solid CAD of them to be able to slice it into layers. The model I have now is hollow and will not work well when put through the slicing software. If someone could give me a solid CAD or explain how to make it solid that would be great. I am very new to any 3d modeling so if you could be specific with your answers that would be great.

Try this, and welcome to the Forum.


Thanks for sending this. The top mobile goal CAD file was still hollow but I managed to figure out how to fill it in. I will post the file’s here shortly so hopefully it will be useful for someone else.
