i made this volcanoe completly in blender and i printed it in black pla then added red hot glue to look like lava and it turned out preety good you could just paint it but think it looks better with hot glue. for the best results you should ues absjust incase the hot glue gun melts the plastic. for even better results print with pla then use a 3d pent with pla to do the lava
