This derivative adds a 2mm hole to each piece into which a cord can be inserted as a keeper. It's a yin/yang thing; one piece requires the other to function and make whole and the cord ensures this.


  1. Size
  2. Print
  3. Insert cord or rubber band into holes and secure each end with a knot or lark's head hitch

For the pictures and as proof-of-concept, a handy 1mm rubber band was used. Any 2mm diameter cord, twine, wire, etc. can be used instead.

What printer and material did you use for the print in the picture? it looks so much smoother than what I can do with FusionForge and PLA

Hey wow, that was quick. I love this site. :-D

I've been thinking about how to keep the two parts together. Some commercial versions have a hinge on one side instead of the clip, but I didn't trust the plastics to bend that often and that far.

In the end I came to the conclusion "Hey - it's a clip. Just clip them together."

But then I like your solution too. There are always people who manage to lose half of the clip, no matter how you drill them.

Maybe one should find a way to encode the parameters on the one side of each part, so that you can re-print the other half if one is permanently lost. ;)

You can use a QR code to do this. Attached is the code for this:

http://thingiverse.com/thing:5627thingiverse.com/thing:5627 foodclip(60,10,15,4,2,2);

It was made here: http://zxing.appspot.com/generator/http://zxing.appspot.com/gener...

And here's a script to covert a QR code into a STL: https://github.com/l0b0/qr2scadhttps://github.com/l0b0/qr2sca... Once converted you can import_stl, scale, and position it on each piece in OpenSCAD.

Yeah, that might be a little hard to decode in a single color on the side of a clip. ;)

Yep. A cord is my solution. ;)

Ha! I guess I'm just not a big fan of these. :-D
