Here is a larger version of my fast printing Ear Saver. Designed for speed of printing and strength. These take 15 minutes each on my Ender 3 printer at 0.2 layer height and three walls at 0.4 mm line width.

I am also uploading my popular "Hero" version and a layout of 10 hero Ear savers to fit 220 x 220 mm ender 3 print bed. I can print ten Hero ear savers in 3 hrs 30 minutes or 21 minutes each. Again, 0.2 mm layer height and three walls at 0.4 mm line width.
