That is very funny. You could call it double irony: what you expected to happen is exactly what happened, but not in the way you expected it to happen.

    clearance=17; // [50]
    height=150; // [300]
    r1=25-17/2; r2=25+17/2;
    for(xy = [[269,73],[85,170],[237,228],[475,280],[263,487]]){
        translate([xy[0],-xy[1],0]) difference(){
            cylinder(r=r2, h=clearance*2, center=true);
            cylinder(r=r1, h=clearance*2+.1, center=true);
        }
        hull(){
            translate([xy[0],-xy[1],0]) cylinder(r=r2, h=clearance);
            translate([237,-228,0])
            cylinder(r=r2, h=height-clearance);
        }
