It's a very small subset of the world that would care about this, but...I'm geeked out about it. I'm making a couple of Swan stations for people so I am revisiting my first one and making improvements along the way.
I figured out how to use some Dida parts in a new way that allowed me to add this little gun locker storage closet to the playset using only one removeable , hinged part. The first one had 4 parts (Wall, roof, and two pieces to hold them together, was a pain to put together and always felt like it was in danger of falling apart. This is much cleaner and easier to use. Yay! Very satisfied.
