Sconce - Arandela

This is my first try into building a sconce to my home cinema room.

That sconce have a large size, 200x400mm. So impractical to most of us. Now i need to find a way to split into parts which fit to my 3d print(200x200x200mm).

Update: new version today 12/09/15(fix the central holes and support of lamp). And i just put the source cad file(inventor format)

New parts splitted and with connectors/holes
