Kite string clip

This is a simple clip for attaching a kite string to a kite. You can tie the kite string to this, and then switch the clip between kites.

I recommend printing in ABS at 100% infill. No supports needed. You may need to sand a bit to fit your kite's string hole.

Not flight tested yet.

Uses and includes my [Bezier library](http://www.thingiverse.com/thing:2207518).

The kite string holder that I'm using is [this one](http://www.thingiverse.com/thing:789726).

Update: Simplified model.
