I've only run smaller experiments so far, mostly focusing around storage containers as I have a lot of electronic stuff that is currently just laying around. You can get some more inspiration here of what you could mould: https://bazar.preciousplastic.com/moulds/
But in general, anything you've seen in the real world would be possible to recreate with your own moulds, the limit is your imagination!
