Simple bayonet mount for 3d printing

Simple bayonet mount for 3d printing.
(Orange color used for selection)

Make tube for inner part, number of sections must be a multiple of 3 (36, for example)


Mark by different colors three equal groups on the upper surface (3 groups by 12 faces). This is not necessary and is done for the convenience of further actions.


Select both edge rings - upper and lower and unselect one edge in every group.


Rotate selection by Y axis. Rotation angle depends on bayonet diameter - 3 degrees in this example.


Unselect all, then seleсt all side faces.


Shell extrude it for making a "spacer" (it will be deleted after). Extrude distance depends on bayonet diameter and accuracy of 3d printer, it can be 0.2-1 (if units == millimeters).


Repeat shell extrude for the outer part.


Delete/hide the "spacer".


Mount part is ready. Form other mount parts as you need.
Something like this:

I use it for restoration of this old thing.
Some parts are missing...

Thanks for sharing ivla. It's always nice to see a practical application of a model.

I noticed you are using the orange colour for selections.
So, I'm just pointing it out in case someone can get confused when see the selected edges that may look like hard edges (which Wings3D's default colour representation is orange).

Thanks micheus.

Orange on gray looks more contrast than red. I think it's important for selection.
Certainly I have to warn about it - and I will do so.
