I barely have space in my study/office/studio, but it does not take up too much. I'm sure people design curtain rod ends or you could adapt models for that. I think there's a cross-over with Lego as you can make custom parts. I do have some Lego, so I could try that. It's a world of possibilities.
!BEER
I looked ... I could do the 3d modelling if I really wanted to, but the truth is they dont bug me that much. :p
The 3d printer getting in my way would bug me more... :p
