Your cylinder is alligned with the X axis.
Try something like cylinder {-z,z,1 etc}in order to have it alligned with
the Z axis.

Replace "difference" with "union" and see what you get. Your cylinder is
turned the wrong way and scaled way off. Try...

cylinder {
        <0,0,0>,<0,0,1>,1
        scale <1,0.04,0.04>
        translate <0.15/2,0.1,-0.01>

    ... but even that could use some fixing.

        scale <0.04,0.04,1>
        translate <0.15/2,0.1,-0.01>
