Astra user says a 3D-printed shower-drain part fit on the first try

A user says they asked GPT 6 Astra (Ultra) to tackle tangled hair in a shower drain using a video explanation that included caliper measurements. They report that Astra matched video frames to the measurements, proposed a fix and provided an interactive sketch. At their direction, it then used Fusion 360 to design a part with adjustable parameters. The user says they 3D-printed it and it fit perfectly on the first try—solving a real-world problem they described as not especially complex.
