Print each of the models separately. there are 3 parts. the Base, the top, and the stencil. For the Stencil you can right click on the model in PrusaSlicer and choose “Add Part” and then use either “Text” or an SVG file to stamp/cutout a design into the stencil. No supports are needed for any of the models.  Its a great way to have a pumpkin you can use every year for Halloween and still keep fresh by just printing a new stencil.
