Insanely simple Cable tidy/strain relief for Anet A8

Fitting a relay as part of an Octoprint installation to my Anet A8 I realiised that cable strain relief was vital so I modeled this quickly, produced 2 and used them. 1 as shown and the other under the PSU. They are a nice tight fit on the cable but cable ties either side of the one shown (at the rear) will provide extra security. A dab of hot glue holds them in place.
