This logo is inspired from the great logo design 'Dark watch' make, by Nerfenstein. (http://www.thingiverse.com/make:63810). I modeled this batman logo in such shape that it makes small steps pattern when printed in low- resolution. (I printed with layer height 0.3). To get the most of this design print with quite high layer height. You can experiment other layer heights to get your desired look. Have fun !
