I am using Ultimaker Cura to print what are essentially cookie cutters - a thin wall that is a silhouette of the shape. I would like to have a broader surface for the top. In Ultimaker Cura, I set it to print a wider "initial layer" but this initial layer is printed both inside and outside the print. Is there a setting I can use to print the initial layer outside the print? I am using Fusion 360 to create the model and would like to avoid having to build this separate layer for every model I build, unless it can be done fairly easily as these shapes will vary for each model.
As an additional question, what would be the best way to split an image into individual pieces - one for the outline of the whole shape and individual pieces for each distinct part of the image, say eyes, nose, mouth - that you would use to build the image after you cut out the pieces? I've tried using InkScape but I am not able to get it to divide them into clean pieces.
