Reservoir with Rollers

Create a new parametric CAD model from zero. Units: mm. Coordinate system: X = width Y = depth Z = height RESERVOIR Create one hollow open-top reservoir. Overall width X = 120. Overall height Z = 180. Front face: Y = 0 flat and vertical. The reservoir expands only toward +Y. External rear profile: - Z = 0 -> Y = 20 - Z = 100 -> Y = 22 - Z = 180 -> Y = 70 Use straight continuous transitions. Wall thickness = 3. Bottom thickness = 4. Top completely open. The final reservoir bounding dimensions MUST be: X = 120 mm Y = 70 mm maximum Z = 180 mm SLOTS Create two horizontal rounded through-slots only through the flat Y=0 wall. Each slot: - total width X = 103 - total height Z = 3.8 - centered at X = 60 Slot centers: - lower slot Z = 132 - upper slot Z = 148 ROLLER R1 Create Roller R1 as a separate solid body. R1: - axis parallel to X - diameter = 8 - length = 106 - axial bore diameter = 3.4 - center X = 60 - X range = 7 to 113 - axis Y = 10.14 - axis Z = 14 R1 must remain a separate solid. R1 SNAP-FIT SUPPORTS Create two supports integrated into the reservoir body. Left support: X = 3 to 6 Right support: X = 114 to 117 Both supports: - shaft axis Y = 10.14 - shaft axis Z = 14 - circular seat diameter = 3.4 - support bottom Z = 9.8 - support top Z = 16 - Y range = 5.9 to 14.4 - upward vertical opening width along Y = 2.6 - opening centered at Y = 10.14 The circular seat must remain below the 2.6 mm opening to form a C-shaped snap-fit. Do not create holes through the reservoir walls. Keep exactly 1 mm axial clearance between R1 and each support. ROLLER R2 Create Roller R2 as a third separate solid body. R2: - axis parallel to X - diameter = 18 - length = 106 - center X = 60 - X range = 7 to 113 - axis Y = 18 - axis Z = 160 R2 must be a solid cylinder. Do NOT create an axial bore in R2 yet. FINAL MODEL The final CAD must contain exactly 3 solid bodies: 1. reservoir including R1 supports 2. Roller R1 3. Roller R2 Do not merge either roller with the reservoir. Do not add: - R2 supports - shafts - motor - coupling - cover - drain - threads - surface texture - other components Keep all stated dimensions parametric. Do not replace or reinterpret any specified dimension.

Parameters

This model was generated without adjustable parameters. Open it in the editor to add your own dimensions.

Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
