Ear Saver Redesigned

thingiverse

The ear reliever eases ear discomfort when wearing a mask. I create these for hospital staff to assist them in helping us. This design is based on Aaron Lu's ear saver model. Initially, I measured it precisely but then made adjustments: I reduced the thickness by one layer. This decreases filament usage (also lowering costs), allowing it to bend more comfortably around the person's head. It applies less restrictive force, making it more comfortable for wearers. BE CAREFUL REMOVING THEM FROM THE PRINTER BED AFTER PRINTING. THEY MAY RIP AT THE END. I added a large trapezoid hole in the center to decrease filament usage further. Then I went a step further and added more slits on the sides to reduce filament usage even farther. I kept the inner lines in the trapezoid for increased durability, so I would not advise removing them as they may become bendy in the wrong places. Note: I designed it to be printed with a layer height of 0.35mm, both initial and following layers. Only change this setting if you cannot print that thick. My reasoning for these changes was to decrease printing costs and increase the number of prints per hour. I can print a batch of eight of these on my Ender 3 in one hour and fifteen minutes, versus the original batch of four per two hours according to Aaron Lu!
