A clip, for clipping things.
The clip was based on the clear clip in the images.
I have uploaded the UG NX6 design files in the zip file if anyone wishes to use them.
To build it download ClipAllParts.stl and print it.
After normal clean up the two clip halves should slide together and the spring slides between the two halves and over the middle.
If it is difficult to slide on you may need to use a knife to smooth the area where the spring slides over.
