A keychain with code snippets to display “Hello, World!” in the terminal in 5 different programming languages, those being Python, Java, C#, C++, and Rust. It is 8 by 8 cm, has rounded edges and a rounded slot for a keychain. The body is 2.25 mm thick and text areas are raised by an additional 2 mm. There are 2 different models, one in Microsoft Himalaya and the other in Arial. Arial is recommended as it is easier to get well-printed text. There is also an inverted one where the text goes into the keychain. I recommend that you print this at a lower speed, 50-75% speed depending on how well your printer handles fine detail like text.
