A Cover for portable monitor - UGame K118 - 18" - Uperfect.
The cover consists of 2 parts. Since the parts are very thin, I would recommend turning on brimming and tree support (technically, the model doesn't require supports).
The model has been printed using 2 wall loops, and 15% Gyroid infill. That is about 400g of filament mass, a good balance between strength and lightness.
The author marked this model as their own original creation.
