Sagging power plugs in wall outlet, diy

Does anyone have any diy advice on how to support heavy power plugs that sag from the wall outlet? I have Shunyata cords and I also have Shunyata's SR-Z1 outlet. However the power plugs still sag. Shunyata sells the Cable Cradle, which is the perfect fix, but I feel like there must be some diy alternative.
