The cord on my A1 Mini's heated bed was being bent at an angle that didn't look like it would hold up for long if left like that. So I modeled up 2 versions of a strain relief to guide the cord into keeping slightly better paths fully-forward and back. Only takes a few mini zip-ties. I'm not a big fan of cable chains and they're extra weight!
v2 is simply an elongated version of v1, I'd print both and see if one helps your wires more than the other, install so the 'back' opposite the opening is bracing your cord from going too far in that direction.
Nice sweeping curves to avoid rubbing abrasion where possible.
