Included herein are keys for the Casio Casiotone MT-28. There didn't appear to be any so far and i noticed srepmub's OpenSCAD library to generate keys that were similar. With a bit of modification (included) and some size settings they appear to work. If not, feel free to modify the library and post it back up!
There's one structural change. This library creates keys with a thicker, anchored post. I'm unsure if the other keyboards can accommodate that but the MT-28 uses a post for the end with much more support than the original model had. These didn't break on my PETG print and still fit the keyboard.
