Hi,

I am trying to design a plastic ring which fits on a human finger that has interchangeable top fittings which can easily be snapped into place and removed for when they are changed.

I have attached a SW 2015 and STEP for anyone to review.

I am having issues with the snap fitting design as I have no experience in this field. If anyone can help me it would be greatly appreciated.

I have not determined the material yet, however when I 3D printed a previous design in ABS (with larger snap fitting than the attached) it didn't fit and broke from the fitting force. I understand ABS is a more brittle material than others and doesn't have very good elastic properties, therefore do not intend to use it.

Many thanks,

Trevor
