The SV05 has a cable duct fitted with T nuts on the bottom rail. I cut this to suit the corner brace and bought a similar sized one from Amazon UK - it has holes to allow cable to pass out (eg the heated bed cables).
I added two holes to allow M3 screws to self cut threads to hold the duct to the brace. I finished it off with more duct up the rear upright.
All printed in PLA at 0.28 layer height, 3 perimeters and 15% infill.
Thank you to Jason Walton for the original design:
