New stud primitive for hips?

[Philippe Hurbain]

Does the name work? hipstud.dat

I'm fine with that

When do I have to also create a lo-res version? Isn't that only needed to fool MLCad?

AFAIK only MLCad complains, and only if "stud" filename is studxxx. Naming it hipstud avoids the issue.

• There is sometime a small difference of the inner diameter of the hipstud. Some hipstuds seem to have a blocked inside.
  It is oddly shaped and nothing connects to that hole. Is it OK to only have one version of the hipstud?
  
• I remember a discusion about the tiny hole on the frontside of the stud on short hips and leg, 41879a and 41879b.
  IMO one version is missing, 41879c, with blocked hole. The printed short legs also have a difference in the  small hole, blocked or  open. Do we need to make all these as correct as possible, or is it enough to only use one hipsstud? Which one? I need to create subfiles without printed surface.
  

imho these are only non-functional molding artifacts and don't need to be modeled (especially since the "stud" is hidden in torso)

No detailed information for Dobby's legs...
