This is an Ear Saver that is designed specifically for smaller 3d Printers (120 x 120 mm). Designed to print fast and still be strong, using 0.4 mm extrusion line width. I can print 4 of these on my smaller printer in about 45 minutes. Lots of these could be printed very quickly on a larger printer. There is only one set of hooks, but they are designed to be slipped on easily and retain the elastic bands, even when not held tight. Can be printed with a variaty of filaments

 

There is a version with the word "HERO" in the middle.
