location behind the GT2 Pulley and the Idler

the Idler Pulleys. Using a long Allen wrench or
a stiff piece of wire (e.g., AWG 12 solid core
copper wire), bend a small hook into one end
of the wire. Slip the short end behind the Belt
and pull it between the Idler Pulleys and
create a loop, as shown.
