The hanger tape is held in place by lining up the perforated holes under the holes that mount the Extruder to the X-Carriage and bolting it all together like a sandwich.
Start by cutting off two short sections of the perforated metal. Sharply bend each into an L shape so that the holes will line up with the Extruder mounting holes. The difficult part is that the hanger tape doesn't like being bent into an L if it is also wrapped around a cylinder such as the PTFE. Clamp it on loose at first and the tightening force of the clamp will bend the metal into a tight fit.
Hanger tape is available in the plumbing section of the hardware store. Example picture here.
To slightly better explain how this works I created this crude drawing.
There is probably a more elegant way to achieve this especially if the Mendel Extruder part were modified.
As a bonus hanger tape also makes an excellent Opto Endstop trigger.
