It was my 3rd Anniversary and I had to try and 3D print some roses for my wife. I found this great model from Thingkinlink, which needed some cleaning up as the model's petals had no thickness, and had problems slicing. Petals were thickened to 1mm.
3 sizes available, an Open large rose, a close rose, and a small close rose.
As per Smoutech suggestion, we allow for a insertion point below the flowers to insert a length of 3mm filament.
