This build is a power cable that runs from an XT90E-M connector to a DJI O4 Air Unit Pro camera system, modeled in Fusion 360 and placed into a full drone assembly. When everything is put together, the finished routing sits between the XT90 connector and the video transmitter, with two separate insulated conductors and terminal housings as part of the completed cable.
The way it comes together is worth studying. The maker starts a new component called Power Cable2, offsets and references faces from the drone connector terminals, then builds construction planes and sketches circles that measure 2.50 mm across. A center guide spline path is drawn between the connectors, and a surface sweep with a twist angle generates the spiral guide geometry. From there, spline curves tie the twisted section back to the termination points, and solid sweeps produce the two conductors.
The detail that stands out to me is the 3D spline with tangent constraints connecting the sweep to the cable ends. That seems like the right call for keeping the transitions smooth where the spiral meets the straight runs. The material choices read well too: glossy red plastic on one conductor, matte grey or black on the other and on the housings. At most two cosmetic details there, and they carry real information about polarity.
One thing left open: the maker usually goes with 600 degrees of twist, but the exact angle used on this particular cable has not been stated. I would like to know whether it changed for this shorter run. My own take is that a fixed habit like that is handy, though matching twist to run length feels worth testing.
