So I'm trying to convince my parents to give in to my plans about my Fort Knox for ducks. I would buy the shed and the materials needed to create a section between the shed and current pen so it is tall enough for me to get to the shed. i could also get kids from school to help me build it, so my parents won't have to help. but they still are saying no, that "we'll talk about it" each time i bring it up, they don't want to talk about it. I was hoping a 3D model could help me show my ideas. i created a 3D plan on the computer, but i would like to make a small model. what can i use to make this? i want to be able to show my ideas about cutting the doors in half and putting wire on the top, so there is ventilation and they are still safe. any ideas on what i could use? i would need normal household items and it would have to be relatively easy. thanks.
