Wall Plug Retainer

Cord too heavy and plug falling out of socket? Here's a handy perch to support the weight. Think of it as a jock strap for a heavy cord ;-)
Print two Angle_Bracket_03, tap them M3 and attach them to Backbone_04 with flat head screws.
After replacing the original with the new Cover_Plate_05, slide the Backbone's nubs thru the keyhole slots and down until it's firm.
Push a 5mm shaft through the outer holes of the Angle_Brackets; a 70mm length works well
Perch another 5mm shaft (or any old stick) across the notches.
Insert plug in receptacle
If you like use zip ties to secure cord to the Angle_Brackets.

--Oopsie! Made a mistake! I've replaced Backbone_04 with Backbone_05. The new one is much easier to print and the mushrooms are applied after it's printed by using M3 x 6mm button head screws.
