as attached draft, I need someone do a CAD drawing and 3d model for my design.
there will be A, B, C, D and E five detials:
1, A is top portion
A-1 is pushing down area for fingers
A-2 and A-3 are two weakenling line where the thickness is only 0.3mm (other place is 0.7mm or more)
A-4 is a wide and thin pole or extension portion connected with pushing area, both sides are widen a little. its thickness is 1mm;
B, lower portion
B-1 is the threads for bottle
B-2 is the sinking portion on B
B-3 is weakening line while its thickness is only 0.25mm and this line stops at point B-4
B-4 is a point where thickness is 0.7mm and width is 0.7mm, so when pushing down, the weakening line broken, the point will hold the broken portion from dropping into water.
C is in green color, which connects portion A and B when molding;
D, is welding line which connects portion A and B together when both portions join;
E, is tiny strips along the outer surface of portion B, depth 0.3mm, width 0.5mm
I have indicated the height of portion A and B, also its diameter.
there is 2 tiny details I will tell you when you almost done the job.
