Inspired by Playmobil (grey) - My green 3D model is in one piece and has feet directly at the bottom, but you can also cut them off and make the couch close at the bottom. Depending on whether you want to print with supports or with filling.

I printed the model with the Bambu Lab P1S AMS and filament Bambu Lab PLA green with standard settings in the Bambu Studio.

I'm still a beginner in 3D modeling and 3D printing.
