The prompt
Position and joint Part 2 and Part 3 onto Part 1 to complete the assembly. PART 2 — Screw Knob: - Move Part 2 so the flat back face of the knob sits flush against the front face of the box (the Y=0 plane), centered at X=197mm, Z=25mm — low and to the right, directly in front of the bottle compartment. - Orient the shaft so its axis is perpendicular to the front face, pointing inward (+Y direction), so the 40mm threaded shaft passes through the 5mm wall and reaches into the bottle compartment cavity. - Join Part 2 to Part 1 with a revolute joint on the shaft's center axis, full rotation, no limits. PART 3 — Telescoping Rod: - Move the outer tube of Part 3 so it stands vertically at the top-left corner of the box, inset 15mm from each edge (X=15mm, Y=15mm), base resting on the top face (Z=150mm) and rising to Z=230mm. - Position the inner rod coaxial with the outer tube, starting flush with the tube's top opening, with the L-bracket at the top pointing outward away from the box. - Join the inner rod to the outer tube with a slider joint along the vertical (Z) axis, motion limits 0mm (fully retracted) to 120mm (fully extended). After positioning both: - Run a drag/interference check on both joints. - Confirm the fully-extended rod does not collide with the tiffin compartment's open top edge. - Confirm there's at least 10mm clearance between the knob's outer edge and the box's front-right vertical corner for comfortable turning. - Report any collisions found before finalizing dimensions.
