Community Print Impresión 3D de MiBunny

Hi, Pierre! Thank you for sharing your nice model. I tried to print it but got a problem. The filament didn't glue to the mass at overhang part (see the picture). I polished it with sandpaper, but the result id not good. Could recommend pls, how can I fix it, Sorry, if my question is too newbie, but I am really a newbie. Kind regards, Pavel (Glumgad)
