Donut Perplex Junior

Slicing a torus is a pleasant mathematical pastime. We entered Donut Perplex with thirteen pieces in the 2019 Design Competition and got little response. Supposing the challenge might have been too steep, we made some simplifications and ended up with four different parts. Your challenge is to restore the torus.
In difficulty, we give this circular discombobulate 2 stars.
