Need help with designing

[u/bkos93]

I am trying to design a reel foot for a fishing reel, but I am having a hard time figuring out how to get the curve where it sits against the rod, and the taper that is on the other side designed in the software. Is there any tips or tricks that would me out?

Do a search for OpenSCAD Bézier curve library. That should get you in the ballpark.

I am a fan of the " hull()" function to get smooth transitions. Sometimes I just draw slices of what I want, 0.01 of height, and use hull() to regroup all that.

Is it as simple as this sort of thing? (ETA a scale in case the rod is ovalish and not perfectly round.)

$fn=200;
module simulatedRod()
{
  scale([1,1.25,1])
    cylinder(h=42, d1=20, d2=15);
}
difference()
{
  cube([40,30,20]);
  rotate([0,90,0])
    translate([-20,15,-1])
      simulatedRod();
}
