This is a lamp shade. Although this is not like lamp shade, it would be decorative lamp holder. It can be use indoor or outdoor. It has screws to hang on the wall. 3d editable STEP file format attached. 3d printavle files also attached. Top portion can be detachable to change the light. Not suitable to hang from the ceiling

For custom size and design you have to contact with me for more details.

Thanks,Mahbub
