Parts for things that came with no drawings: each measured from photographs of the original, then modelled, printed, and fitted.

The desk’s counterbalance cable pulley had a non-standard spiral groove that wound outward at a growing radius. Took its geometry from photographs, modelled a replacement, printed it, and reassembled the desk.

An AMVR battery with a non-standard curved profile, mounted on the VIVE Deluxe Audio Strap (DAS). Photographed the battery against a measurement grid, took its curvature from the image, and designed a thin, hollow snap-on adapter to keep the added mass down.
