First Responder Door Jamb

Inspired by the PLaperriere 9mm version.  This is an excellent door jamb and when you are entering a building where the door locks but you want someone else behind you to enter with ease I suggest this door jamb!  

I modified the hole for paracord to go in easier and adapted the infill/walls for a stronger jamb than the original.  I also reduced the speed of the print significantly to help TPU print well. I have successfully printed 9 on a plate without stringing issues on the H2D. I have only printed in TPU-95HF but will try TPU-90 soon.  You can add text on top if you like I would suggest utilizing PETG for better adherence for text.

To increase functionality I suggesting adding 10.5" of paracord.  Be sure to burn the ends.  Run it through the door jamb then add a 1" in length of 3/8" heat shrink tubbing.  Then tie a knot and pull the heat shrink over the knot.  It may be easier to use ½" heat shrink tubing but I like it as tight as possible over the knot.
