Bungee Cord Hook

Simple hook for 1/8 inch elastic cord, I used these to make some lightweight cords to hold my sleeping pad on to my backpack. Just push the cord through and tie a knot, I use a figure-8 knot.  A little glue can be added to the knot for peace of mind.  I used bulk elastic cord off of amazon.

This is intended for lightweight purposes, like a sleeping mat or outer layer, the hook is sized for something small, no larger than 3/16.

I suppose it could be scaled up for larger cord (1.5x for 3/16 cord)

Print on its side with no supports, add lot of perimeters rather than infill for more strength.
