Simple rocket for Duplo figures, which I did for my kids. Top can be opened to insert/remove pilot. I hope you will enjoy it as my children do
For black top, use at least 4 perimeters. For the rest 2 is ok. Print taller things alone, so you dont have problems with different layers due to temperature difference as I had on top part with windows.
Everythong is simple, just glue it with CA glue. Deck is glued to bottom part.
