Air-Operated Drill

All Items are in a group. The knurl on the handle is a separate object if you wish to omit. The hose is a curve object with hooks on the endpoints – one parented to the drill and the other to the fitting. To re-position the hose, move the objects into position, then edit the curve. I would just delete all the middle curve vertices (keep the endpoints) and re-subdivide rather than moving the existing ones.
