My husband likes to use the Unstoppable T-rex meme (a T-rex holding extendable arms) as his cover photo/avatar at work. As a birthday present, I made him a personalized business card holder. I used the Blank Business Card Case by AlexMu, and added the image and text to the cover. I printed it as a multi-material print, but you could also print each part separately and glue them together. The T-rex design and text are imprinted into the case, so should be flush when printed as one piece or assembled from separate pieces.

Print the model upside down to avoid the need for supports - if your first layer calibration is good, the design and text should still come out well. I printed in PLA, at 0.4mm layer height, with 15% infill.
