I designed this great-looking low-poly coaster to demonstrate how you can use PrusaSlicer's built-in features to turn a solid object into something amazing. It uses modifier meshes to change the infill settings in different locations and layer heights to create a fantastic-looking interior design that also adds loads of extra surface area for condensation to evaporate, making your drink stay cool a little longer.
IMPORTANT PRINTING INSTRUCTIONS: Use the .3mf file, not the .stl! The .stl file is included in case you want to mess with it or make something equivalent to the .3mf in a different slicer. Also, the .3mf was made with PrusaSlicer and has only been tested with it.
