Initial, 13th Birthday Card
thingiverse
A birthday card cover for my sister's 13th birthday a few days ago, going to see the family in a couple days. Although this model isn't easily modifiable, you could use it as an idea for making your own. Search for .svg files to make your own. Or if you coincidentally have an acquaintance who's turning 13 and their initial begins with R, then here you go. It's mainly an inspiration for those who can develop more easily modifiable versions of the same thing to provide downloads for the masses. The letter is lifted to add differentiation in the print. Perhaps take some paint to the surface of the lifted letter. I wasn't super careful with the message part, so the inner part of looped letters will be removed and hollow after you print.
