Print the Monitor_Main_Hand.stl file with 100% infill, and the Monitor_Base.stl file with 15% infill. Set the top wall to 4 layers and the bottom wall to 3 layers.
Ensure the orientation matches the one shown in the provided photo, as this setup worked effectively for me.
Once printed, securely attach the Monitor_Base to the Monitor_Main_Hand with glue to ensure a rigid connection.
