This is a coaster I designed to be printed in multiple colors. If you have a MMU or similar, it should load and print as is. I have also included a single color version for anyone who wants to just print it that way. If you don't have a MMU, you can still print it in full color with one extruder, it just requires a bit more work and some patience. I have included a PNG file documenting the way I was able to print this with just one extruder. This experiment was done using PrusaSlicer and a Prusa i3 MKS, but it should work on other printers as well.
