ear saver

thingiverse

I was really impressed with this ear saver design, as it's much more flexible than the other main ones being printed and uses significantly less plastic. I needed one that was slightly longer in size, and this one fits the bill perfectly at about 180mm wide. I'm happy to report that I can fit seven of these on my Ender3 printer and a whopping eleven on my CR10S - maybe even more if I really pushed it. Print times are running around fourteen minutes each for the ear savers, which translates to just over an hour and forty minutes total on the Ender3. To get the perfect print, I tweaked some settings to ensure that all horizontal and vertical lines were smooth walls with no top layer pattern - exactly as seen in the picture. This modification shaved off a couple of minutes from the overall print time. Here are my customized print settings: Nozzle size: 0.4mm Layer height: 0.28mm Line width: 0.5mm Number of walls: 4 Top layers: 5 Bottom layers: 3 To achieve flawless prints, I also adjusted the horizontal expansion to -0.05, which eliminated any zigzag patterns on the vertical parts of the hook. When set to zero, these areas were plagued by yellow zigzag lines. Lastly, I bumped up the print speed to 80mm/s from my default 50, and set the wall speed to 40 (as dictated by Cura).
