I am looking for some help creating cookie cutters. My sister has a baking company and I have a 3d printer, so I figured I would help her out and create some cutters for her. While some of my cutters work ok, most have ugly jagged lines or thin walls. The STL files have multiple errors in the mesh and even running it though netfabb or Rhino will fix some but still looks bad. I am using the Adobe Illistrator/photoshop way and it seems straight forward, just something is off. Can any one help me out? Thanks
I have found that if you size the wall of the cookie cutter to print with two wall layers, no tapering to an edge, it works out perfectly (about .030 in. for me using simplify 3D). Sturdy enough to cut, and it prints with the walls fused together. I experimented a but and found a great profile for cookie cutters that works for nearly any design. I’d suggest you do the same. Develop a wall profile that works, and use the same profile on all the cookie designs. I use fusion 360 (free). it is very repeatable and works great. If you can send me an example I could take a look at it.
Thank you for the reply. I have been trying and getting very frustrated with this lol. But I will have a go with your suggestions. I uploaded the picture i was using and my STL that was created. I also have the photoshop files if you want me to email them to you. Thanks for your help.

I may need some hand holding on fusion and the wall profiles you were talking about. Still very new to 3d printing. 
The .stl file you made looks pretty good, I think you are almost there. It appears that the program you’re using makes the lines blend together when it extrudes. Can you try thinner lines or pull a few lines of pixels off the edges? or is this after adjusting with Rhino? The detail lines in the middle are definitely a tad too thick and if they were a tad thinner, it might work.
