This is a remix of my parametric lens collar featuring an additional parameter that might be extremely useful: You can now change the angle of the flanges. This is crucial whenever the collar's position on the lens is close enough to the camera for one of the flanges to collide with the camera's grip when the lens is attached to the camera.

Originally, I planned to replace the original model file by this one, but my first tests have shown that the additional parameter causes the others to get in each other's way too easily. Although it's still possible to use a far-bigger-than-usually-needed range of values, the original model is a lot more robust concerning interaction of parameters, so I decided to upload this new one as an alternative rather than a replacement.

How to use

Well, using the file works just as with the original one (if you need instructions, you will find them here), but there is one additional option now in Fusion's User Parameter dialog:

By entering a (positive or negative) angle for the “FlangeAngle” parameter, you can change the positions of the two flanges on the collar ring. Obviously, this value can not be changed arbitrarily. The range of acceptable angles depends on the ring's outer width - the larger the ring, the bigger the possible angles (as the flanges must not collide with the foot).

The safest way to get the desired result is to enter the parameter values in this order:
1. FootLength
2. MainDiam
3. MainThick
and then the rest of parameters in arbitrary order.
If this does not lead to the desired result, please don't try to re-change the values. Instead, click “OK”, then undo (Cmd/Ctrl-Z), and then open the Parameters dialog anew.
If there's no way to get the collar you want by using this file, please notify me via the comments section, and I will se what I can do. Nevertheless, there's still the older/original file which, as said before, is more robust concerning the range of possible parameter values.
