How to form a tapered stamp from an SVG I am trying to make a stamp from an SVG. I have found a model on thingiverse that demonstrates the desired outcome well.

Given an SVG, and a "body" mesh:



I would like to make a stamp where the body tapers into the impression:



I am very new to blender, and have been trying all manner of boolean operations and extruding, but am stumped on how to create something as elegant as this - preferably without lots of vertex nudging.

I believe the example was done in fusion 360.
This result can be achieved easily using basic operations.


Connect parts of your shape, so it only has one edge (select 4 vertices and press F and repeat)  
Connect it to a circle (or your handle)
Add some ridges and move your shape upwards to taper it.


Make one outside edge and connect it to a circle (or other shape)



Extrude it to make a handle (unless you already have one)



Add some ridges and move the shape upwards, it will taper nicely.
