Hi, I was trying to print a rocket from Thingiverse (http://www.thingiverse.com/thing:50178) but the print was screwed up near the start. The plastic for the 4 legs stuck to the extruder and the result can be seen in the photo below. Help pls!
P.s. I can print some stuff properly such as http://www.thingiverse.com/thing:47032.
