If the square is 50mmX50mmX50mm, the empty ball is 55mmX55mmX55mm in the center. It seems hard to do in Fusion 360, it will show errors.

Wow,
I managed to do this, but it took some 10..15 minutes! Used joints, magic/luck and the 'Modify > Combine > Operation: cut' tool.
I think the real challenge is: how to do this in 10 sec?
(will leave instructions for others - my Fusion just beachballed anyways...)
btw:
- try the scaling when posting images (very handy)
- would you tell more of yourself & which 3d printer company (ad requested!) on the 'General > Introductions' thread 🙂
Hi George!
I was able to do this really quickly using a Rigid Joint feature. I was able to convert the bodies to components, which enable me to use Joints to position the components. See the video below for more detail.

I hope this helps. Let me know if that works for you. I'll be happy to look at it from another angle.
Thanks,
I have complete the work as your instructions, and I combind it to cut the ball to complete it.
But after I do all works, it can not fillet the edge, it will show errors, if you do fillet after combine it.
Could you give more specifics on how you tried to do the fillet, and what errors came?
I'm able to do fillets (5.0mm) though for some reason I needed to do them edge-by-edge, mostly.
At the lower right corner of the window I see these errors (but they don't really seem to hurt):
Hey guys,
I reviewed this workflow, and I think I have an understanding of the warning message you are receiving. Whenever I use the combine feature in the below video, I do not check the Keep Tool option. This effectively deletes the sphere body from component 1, causing the joint that was used to position the sphere to fail. You'll note that after the combine feature, component 1 no longer contains any bodies.

In contrast, if I choose to check the Keep Tool, the body remains in component one and the Joint will not fail. See video link.

The warning message is letting you know that the joint has failed, however, this does not affect the geometry of the model since the tool body was deleted. At this point, you could choose to delete the Joint and move forward with the body created from the combine feature, or you could choose to the 'keep tool' option in case you would like to come back to the cube and sphere in the future.
Hope this helps clarify the warning message. Please let me know if you have any questions or feedback about any of this.
Thanks,
Just a quick note on warnings and errors. The message seen in the picture above is a warning (not an error). Warnings are messages that are typically not fatal enough to stop the operation or workflow. They are shown with yellow triangle as oppposed to errors which are shown in red circle.
Hope this helps.

Hi Nate,
thanks for a good description on what's going on.
However, what would be the use case for wanting to keep such an orphaned joint around? I don't come up with any.
In other words, isn't the "keep tool" checkbox unnecessary. When deleting an element with joints, Fusion 360 could always remove any joints attached to an element to be removed. That would be simple, and what the user (at least I) would expect. This leads to not needing the warning messages, either, since the 'broken' state would never be entered.
Another issue (if the warnings are to remain) is that the wording in the browser warning is somewhat funny:
Just remove the "Joint's" - if the warning cannot be eliminated (best error messages are those that can be removed).
...(cont'd) (too bad the forums don't allow editing earlier entries)...
What I meant by removing a joint is removing the half that belonged to a deleted object. In the particular case, the box's joint would remain, but be open. Unjoint joints would naturally be completely gone.
