Base for H11 vehicle type lightbulb (PGJ19-2)

For an illumination project I want to use the ubiquitous H11 Automotive Type lightbulb. Pictures are from my test cuts.
This bulbs use a base defined by IEC 60061 standard referenced as PGJ19-2. The geometry and dimensions where taken from the standard.
The SVG files are designed to cut the base from the front, the lightbulb will be inserted from the oposite side from the cut side.

1/4, 1/8 and 1/16 bits
For cutting I used 1/4, 1/8 and 1/16” carbide bits in decreasing size order. Pay attention to the maximum depth of cut for your 1/16 bit, it might bump against the triangle on the top right hand side that is used to stop the bulb rotation.
I could not find the oficial wall thickness but after some experimentation it looks like 3.0 mm works good.
The file PGJ19-2-H11-cut2.svg is optional and is used to cut a pocket to better retain the bulb and should be about 0.8 mm.
Only use this for LED lightbulbs, the traditional H11 Halogen lightbulbs dissipate 55 W and the thermal management is very complicated. The LED ones dissipate about 15W that still requires considerations for the heat but is more manageable.
If there is interest I can upload the Fusion 360 CAD file.
