Make your own Duct Tape neck ties with this clever 3D printed clip. Simply:
Print the tie clip
Unroll aprox 3' of duct tape and lay it face up
Cut the tape from a little past 1/2 way on one edge to near the other side to taper the tape strip.
Unroll another length of tape approximately 6" longer than the tapered strip
Fold at tip in one side of the longer strip.
Lay the tapered strip sticky sides together on the longer strip with the wider end near the folded tip
Fold the sticky sides in following the taper.
Now that the tie length is done, give it 19" for adults or 14" for boys and make a back twist, wrapping the thin end around the front of the tie.
Tuck one end of the clip into the knot made.
Wrap the tail around the back of the clip and tuck it under the knot, behind the long end, but in front of the clip.
Pull both ends of the tie to tighten the knot.
On the back bring the two sides together and secure them with a small piece of tape to give the knot it's shape.
