Glass Shelf Dimensions of 3.0 Single Wide Display Case?

[Blockster]

Hi All,

Hoping someone can provide me with the glass shelf dimensions of 3.0 Single Wide Display Case (minus the front lip that comes out) Measured myself a few weeks ago but forgot the paper at home and was heading to a glass cutter on the way home from today. Any help appreciated.
