Three-channel cable guide

Use Nora3D native parametric CAD operations. Work in a new, named document owned by the intended user. Units are millimeters. Inspect the bound document and supported operations before writing. Use current native IDs and returned replacement IDs; do not guess face or body identifiers. Save and reopen the final model. Preserve editable feature history.

Expose only the parameters listed below. Keep all other dimensions fixed. Use English public labels and descriptions, even if the native kernel uses localized internal variable names. Do not claim a physical print, load rating, injection-molding suitability or exact recreation from the prompt alone.

Create Guide: X width 60 mm, Y depth 20 mm, Z height 12 mm, bottom center at the origin. Create three cylindrical cutters named Channel 1, Channel 2 and Channel 3, radius 3 mm and length 40 mm, bottom centers (-18, 15, 12), (0, 15, 12), (18, 15, 12). Rotate each cutter 90 degrees about X through its own bottom center, so its axis points along negative Y. Query current geometry before each transform and use the returned replacement body IDs. Subtract all three cutters from Guide. Their axes lie at the upper surface, creating three open half-round grooves. Do not describe this part as a snap-fit or locking clip.
