General:

I modeled the model with the program Shapr3d and I tried to create this so that the thickness of the window and blind can be changed variably. The model is provided as .shapr, .step, .stl file. If there are any suggestions for improvement, let me know in the comments and do not be afraid to remix the model if it does not suit you.

Print:

I printed the model with white PLA+, used 10% infill to get some flexibility. However, you can also experiment with the infill if necessary. A print speed of 75mm/s worked well for me.
