This is my first 3D printer @i3dbot . First time I started using it, I was a newbie in slicer settings. There were no explanations of settings and no good slicer was existing by that time for RepRaps, in 2013. My first successful print was the propeller in the darkest color. This year, I wanted to sell it to someone who can use. But, before I sell, I wasn’t liking the pulley of its belt system, I had to modify that. I modified it with 4 608zz bearings and some flexible prints from MakerBot. Last print I got from it was the same propeller I printed when I first got it. Among the light colored parts, the one on the left was printed on MakerBot, the one on the right was printed from i3Dbot after making modifications and by using @simplify3d .
