Diggro Alpha 3 (Longer LK4 Pro, Alfawise U30 Pro) hotbed cable strain relief

I have my Diggro Alpha 3 in a Ikea Lack enclosure, so the strain relief by @Earthbound_ wouldn't work for me, as it would cause the cable to jam into the back wall of my enclosure. I took the design and simply angled the support arm up 45 degrees to allow it to stick out less from the back of the heated bed, and also to more closely follow the angle of the cable as it loops up and then back down into the cable tunnel in the floor of my Lack enclosure.

So far it works great. I can position the printer so the bed won't hit my front door when fully in the forward position, and doesn't push on or kink the cable when it is in the fully back position.
