tube with ultrathin walls

Looking for possibility to produce tube length 35 mm ,OD 2.7 mm ,ID 2.5 mm .
Ability to handle axial load up to 100 N without bending
Tapered end length is about 3 mm (could be adjusted) .Front hole is 2 mm diameter on tapered side
2 funneled side holes 4 mm away from tapered end
Can you please outline for me approach/area of composites that can meet these requirements
Cannot attach stl file

Without some kind of drawing/image, this is very hard to suggest any approach to... My initial impression is that it will be very hard to do in a CF composite.

You are expecting it to handle a load of slightly above 10 kg perpendicular to the tube, without "bending"   = Not possible, it will bend, question is how much you can tolerate.
 With a wall thickness of 0.1 mm and a length of 35 mm ..

I could probably make such a tube from Beta-titanium --- I would not care to speculate on the price though ... CoolWhistling
