I like to print these face down on a textured PEI plate so you cannot see any of the directional lines from the toolhead and the text side has a glittery finish.
These are quite small - only 66% of the original size - so you may wish to scale up if your slicer cannot handle the small details. Ideally this is printed in Bambu Studio to use the AMS, so a 3MF file is included.
If using the included STL files, you will have to separate the shells of the text from the heart. This can be done by right clicking on the model > separate > to parts (if possible).
For non AMS users, you can also achieve the flush dual tone print by slicing the letters first, printing in one color, and then switching the color, printing the body on top of the letters.
The author remixed this model.
