About this 3D model

Here is my attempt at the detail of the Deckard's blaster. It's not perfect - the hole is not going through when I try to 3d print. But otherwise - looks more like the original. As for the drum cover - nothing major here - just added two hex bolts on the cover to make it look like the prop. Thanks the rest of you and especially Andrew Forster for the initial 3d model.
