This is a larger version of the granary prop grain_sack. It comes with 4 skins. 2 of which are the original skins for grain_sack and the other 2 being some custom skins I made. They are specifically made to mimic the size of the barrel_crate_half prop.
This model was made by simply stretching the original in blender, so let me know if there are any issues with it.
