Yes you can U47. They are available from Shapeways as a 3D printed key. Someone from GH ordered the key and said it was wobbly. Maybe a drop of super glue between the 3d printed key and its key stem would help? Also the color does not match the other keys and the key is unprinted (no text on the key).
If you want it please add 9 units of the item “other customizations (in $1 increments)” for the key + shipping from Shapeways.
