You can easily do this with a Bezier Curve object.

There is a builtin addon shipped by default with Blender that allows drawing spiral objects. You can activate it under the File > User Preferences > Addons > Add Curve: Extra Objects.

Then on the 3D View add a new curve type object, from Add Curve:Spirals > Archemedian

Adjust paremeters to your liking, more importantly Height, Radius and Number of Turns. You can also use Radius Growth although I fear it is insufficient alone.

After creating your base spiral, you can enter Edit Mode in it, activate Proportional Edit , select a buch of spiral loops as desired and use scaling to change the radius into that smooth shape.

Be sure to use S, then Shift+Z to restrict scaling to the XY plane, so it will only make the loops thinner/fatter, without moving them in Z axis.

• I went into user preferences and added the extra curves but there is no option to add an archemedian curve – Helpmeplznohate May 11 '17 at 17:43
• Try Shift + A > Add > Curve > Add Curve:Spirals > Archemedian in the 3D view. Make sure you are not in edit mode under another object. – Duarte Farrajota Ramos May 11 '17 at 17:50
• Is it supposed to be like a little sub menu thing? – Helpmeplznohate May 11 '17 at 17:56
• It is under a submenu, check the included screenshot in my answer. – Duarte Farrajota Ramos May 11 '17 at 18:00
• I can't see any screenshots I'm on a school laptop also i don't see any sub menus under spirals – Helpmeplznohate May 11 '17 at 18:06
