Prusa I3 pro b dust filter

I did not create/designed the parts, I just merged the two components.
I used support for the file "tube.STL and tube_right.st".

My designs are Tube.stl(left) and tube_right.stl and the main model that I modified was based on the levers from "http://www.thingiverse.com/thing:1693605".

note: the parts belong :
1 - http://www.thingiverse.com/thing:1693605 "Left_cover,Left_base,right_base,right cover"
2 - http://www.thingiverse.com/thing:153807 "Cap"
