3d model issues, minor ig but you could repro and fix

the cables look funny, worth to repro and fix, but minor issue

Reroute USB D+ and D− as a proper differential pair.
From the published Circuit JSON, the connector-to-series-resistor routes are approximately 53.7 mm and 42.6 mm, use five and three vias respectively, change layers differently, and are not coupled. The RP2350 guide calls for approximately 90 Ω differential routing over an uninterrupted ground reference, with the 27 Ω resistors near the chip. The resistors are correctly present, but the long upstream routing does not follow that guidance. This needs a reroute or USB full-speed compliance/eye testing before sign-off.

very large skew, it may cause issues
