2D jpg to 3D print file?

[ScottB]

Hello,

I'm new to all this and all I want to learn to do is take a 2d image adn use it to create an embossing stamp. What software would you reccomend t do this well? I've tried 3d Builder and it leaves the edges a little ragged and the depth of the lines changes whe I try to slice it.

I've attached a file of the type I'm trying to 3d print.

Any help is greatly appreciated!
