**To skip these steps, use the .3MF file and import it into prusaslicer, it has the settings premodified**

Once you import the .STL model into prusaslicer, you may have to split and rearrange the different coasters because they were designed for a bambu lab P1S build plate, depending on which printer you are using.  You do have to spit the coasters to the seperate objects no matter what.  Click the box on the right of the screen next to each of the model names with the label “Click the Icon to Change the Object Settings”, and select the infill option, as well as the layers and perimiters option.  Change the individual infill of each object with the section under where the model names are listed (You may need to change the mode to advanced or expert to see these settings).  After that, change each object so that it has zero top solid layers, in the same spot where the infill was edited.  In that same section, you may need to change the number of perimiters to 4-5.  Then, in the section above the model names, change the infill to whatever density you would like the coasters to display (I find that 10-15% displays the infill the best).  After that, add a color change on layer 4 and you're good to hit print!
