C9 Pixel cover - Improved

This is improved from my original version http://www.thingiverse.com/thing:1243507

It is not a remix but a completely new design done in Fusion 360.

The shape has been made as close to a classic Incandescent C9 bulb as possible.

The base features a 13mm thread that will screw down over the soft plastic surrounding common LED Pixels used in Christmas lights. I have tested this on quite a few different pixels I have and it provides a secure fit that is far less likely to come off than the original push fixture.

The shell is 0.8mm thick in the design aimed at two perimeters using a 0.4mm nozzle.

Three STL's are provided, one is a classic smooth exterior and the others features random facets that give an external texture but don't really change the light too much

You could print in translucent colours for white leds.
