A toggle button that can be threaded on shockcord. The purpose of this is to attach a backpacking quilt to a sleeping pad. The quilt has small nylon ribbon loops, that the toggle will be pushed through to keep the quilt attached to a shockcord loop around a sleeping pad.

The toggle will replace the figure 8 shaped mitton hooks, which are difficult to use, and I've had them come undone at night.

I printed this in glow in the dark PLA to assist in use at night.

Also attached is the OpenSCAD file if you'd like to customize.
