Hello i just joined 3d printing have done few prints not very successful but getting there . However this is not about printing it self this thread is about 3d modeling , i am trying to convert blend file to stl .but i am getting some weard stuff going on and not sure why .
this is blend file :


i downloaded this file from cgtrader and only one format was blend . so i open it with blender and exported as STL
how ever when i open with chitubox and try to set up for printing model its self looks bugged or something :


can someone tell me if iam doing something wrong when converting or does blend file need some adjustments to be able to convert property and print ?
