Outdoor Wall Lamp

Here is a design of a exterior wall light. Inside there are two supports to thread an E27 ceramic lamp holder (see pictures), and a passage for the wires.
The diffuser must be printed in clear filament, and does not need to be transparent.
Maximum Bulb diameter 74mm.
Two holes for attachment to the wall with 5.5mm of diameter and 64mm apart.
The rear face was made hollow to allow its installation in rough or not perfectly flat walls.
The diffuser is available in two versions with 1.2mm of wall thickness as well as 0.6mm. It was intended to be printed with a 0.6mm nozzle ( 2 walls or 1 wall ).
Diffuser diameter: 145mm.
- To print, take: ''Lamp Round.stl' + (''Diffuser 0.6mm.stl'' OR ''Difuser 1.2mm.stl''). -- SUPERSEDED -- See Update --

**UPDATE: 13 Feb 2024

Corrected interior chamfer, to maintain the part thickness along the edges. Original file was removed and replaced by "Lamp_Round_Fillet.stl".
Added a new base part, identified as "Lamp_Round_Chamfer.stl", with Chamfered instead
