This Twilight Zone Piano-mod is a 3d printed in PETG with a beautiful wooden texture. After printing this mod then gets fully sanded and painted to minimize the 3d printing artifacts. 
Installing this mod does not require any irreversible changes to your machine. It only needs a Philips head screw driver (preferably long one).
Although PETG is pretty resistant to heat, This mod requires using LED bulbs (preferably low profile ones or without the dome).
Feel free to contact me for any other questions.
