Three letters fused into a single block. Yes, like the cover of Gödel, Escher, Bach. Yes, one of the letters can be a heart. :-)
Not all possible sets of letters work, so message me with your choice before ordering!
This will be 3/4-1" tall (2-3cm) tall, depending on which letters are chosen. If you want, happy to give you the STL file so you can print it at different sizes.
