The prompt
Modify the existing CAD model without rebuilding or simplifying the reservoir body. Keep all existing reservoir geometry and dimensions unchanged, including: - body height: 150 mm - top external size: 140 x 120 mm - wall thickness: 5 mm - top internal opening: 130 x 110 mm - flat rear mating wall - bottom drain hole: Ø12 mm - two rear slots: 103 x 3.8 mm - lower slot: Z = 120.2 to 124.0 mm - upper slot: Z = 136.2 to 140.0 mm - keep exactly 10 mm of solid wall between the top edge of the upper slot and the reservoir rim at Z = 150 mm. Do not move the slots higher. Add a removable low-profile top lid as a separate solid. Lid: - top plate thickness: 3 mm - maximum closed height: Z = 153 mm - no handle, knob or feature above Z = 153 mm - plate size: 144 x 124 mm - centered in X - rear edge flush with the flat rear wall: no rear overhang - 2 mm overhang on each side - 4 mm overhang on the front side to provide a grip for removal. On the underside of the lid create a rectangular internal locating flange: - external size: 129 x 109 mm - wall thickness: 2.5 mm - depth: 8 mm downward from the lid - centered inside the existing 130 x 110 mm opening - clearance: 0.5 mm on each side. The lid must be removable vertically. The reservoir and lid must remain two separate solids. When the lid is removed, the full 130 x 110 mm top opening must remain accessible for hand access and belt removal. Do not modify any other geometry.
