Hello choco, I changed the code as following: extra_w=2; top_w=2.8; bottom_w=top_w+27.3-26.9; //bottom_external - top_external height=5; module lampfix2d() { translate([8.06,0,0]) polygon( points = [ [0, 0], [0, height+extra_w], [-top_w -2*extra_w, height+extra_w], [-bottom_w-2*extra_w, 0], [-bottom_w -extra_w, 0 ], [-top_w -extra_w, height ], [ -extra_w, height ], [ -extra_w, 0 ] ], paths= [ [0,1,2,3,4,5,6,7]]); } rotate_extrude(convexity=10) lampfix2d(); because of the ; after the module statement, openscad "sees" this as an empty command. Further I think Openscad does not like a negative value for the translate in the rotate extrude. Regards, Kok
