One of my hobbies is soap making, so I created this print to be easy to customize using Prusa slicer's "Add modifier" feature.

Right-click the "puck" in the slicer and choose Add Modifier. You can either use an artistic design in svg format, or type any message. Choose "cut" in Operation and the soap will fill in the negative space, leaving your customization on the top of your soap.  

I made this stl with TinkerCad, and I print these in TPU, so they are easy to remove the cured soap, without scaring your soap, or ruining your custom design/text. 

Happy Making!
