This is really cool! I'd be interested to find out what lower cost / recycled materials can achieve with this design. Also designs for the other connecting pieces like chains etc
Solid objects aren't always stronger, strangely enough. I'm no mechanical engineer, so I can't explain it. I assume it has to do with how stress is tranferred.
If there are bending forces on the object, the middle of the structure basically doesn't add any strength. If it's in tension or compression, it does.
For this challenge, with the 50g weight limit that has bending forces, a hollow object is always stronger. If he filled in the middle, it would add more weight for very little additional strength.

That was fun. Thanks for posting that. All that weight and it was hollow. If that was a solid print it would have held 10,000 kg

Maybe, maybe not.

Neat! Thanks for the insight

What about a honeycomb-like filling, mostly open, but with walls strengthening it?

Ok I'm wrong

Love to learn though, I would have thought the same
