Measure the real setup
Measure width, depth and thickness with the everyday case fitted. Include camera bumps, watch bands, cable heads and any grip or wallet that stays attached.
Show the connector direction
Photograph where each lead enters and where it should leave the desk. A cable path needs bend allowance and strain relief, not only a hole at the connector centre.
Check the proof at full scale
Review the stated dimensions and device names before approval. A later case or hardware change is a new fit decision and may require a replacement insert.
