Keycaps and Alternative Sized Key
Once you've completed your keypad, consider topping off your keys with a keycap. There is a ridiculous variety to Cherry MX keycaps -- they vary by color, translucence, height, labels, and size. Below are a few options available in the catalog to top of your Cherry MX Switch.
If you are looking for more options, there are plenty of keycap sources out there, including WASD Keyboards and MechanicalKeyboards.com. Once you have chosen your keycap and placed it on the key, it should look similar to the image below.
Or consider adding a key that is four times its normal size to your project!
