IKEA Tertial Bottom Steel Tube Strengthening Insert

I made this since my the bottom part of my IKEA tertial lamp was bent… 

I designed this in Fusion 360, made to slide into the bottom of the steel tube part of the lamp.

Its drawn with a diameter of ø9.65 mm to slide in the pipe that was ø9.69mm .

I printed it with some extra perimeters for some extra strength (see screencap.) and laying down for best layer adhesion relative to the forces it is exposed to.
