I think I will need your help making the "rod".

You can do it! Look at the bottom of the file; I've commented out a cylinder "//simple platform for Cody".

translate([0,0,2]){cylinder (r=20,h=3,center=true);}

First change r and h - note that the height expands from the middle so it sticks out the bottom.

translate([0,0,2]){cylinder (r=2,h=30,center=true);}

Then change the "z" value in the translate function to slide it upward. You can move it up by half the height, plus half the thickness of the cylinder. Overlap is OK.

translate([0,0,17]){cylinder (r=2,h=30,center=true);}
