The charging / multi-port cable for my Surface Pro 6 has rather a flimsy cable, and I am slightly worried about it breaking. (I’m not hugely worried, and replacements are not too expensive, but anyway…)
Someone else had the same concern, and they’ve made a 3d-printable strain relief thing.
It printed easily, and looks like a bug from the Matrix.
(Sorry for the quality for the photos — taking photos of matte black resin doesn’t work too well.)
FWIW, the cable on the Surface Dock adapter is much chunkier, and I don’t have the same concern.
