Anet A8 (stock) extruder cables strain relief

Strain reliefs are aplenty, here's my take:
An easy to install cable strain relief for the stock extruder of the Anet A8 (2017).

Installs with 2 very small zip-ties, 2mm wide. Tighten well, and cut the remainder tip, closely (see pictures). Check for a snug fit.
