Ceiling Lamp Extender

Here are the files for my lamp extender project.

I modelled some parts that would make the cable exit look nicer (and keep the cable away from sharp edges) and hold the lamp socket cover in place.

It was made to fit the cover for the IKEA Melodi (38cm) lamp. So the "Melodi" model files will only work for that lamp.

The whole arm is made out of:
- Two pieces (900mm and 100mm) of 4040 T1 T-slot aluminium extrusions.
- One angle bracket with matching M8 T-slot fittings.
- One M8 T-slot fitting and a M8 screw eye.
- Two plastic endcaps for the exposed sides (store bought)

The "backing" part has a lip that should rest inside the T-slot channel.
Together they sandwich the cable and then you push the whole assembly into the extrusion end.
Note that the pegs that fit inside the extrusions corners might need
