I bought a henon headlights for my GreatWall Voleex C10 and needed to drill the caps to insert the cabled to the electronics. But instead I decided to design and print a cap with hole in it with the desired size. In the past I managed to lose a cap and it was quite hard to find a replacement so I think this could help anyone with that problem. The included FreeCAD source file is quite generic and I should not be very hard to adapt for other cap designs/sizes. The model has supports for the locating pins which must be removed before installation.
2019.04.17 Made some changes to the source file and added chamfers to sharp edges.
Any comments, suggestions, makes,.... are appreciated :)
