Planar Compliant Gripper

Create a 3D CAD model of a symmetrical 2D planar compliant gripper mechanism extruded to 8 mm thickness along the Z-axis. Generate the 2D sketch on the XY-plane by constructing the right half (X >= 0) and mirroring it across the Y-axis (X = 0) so there are zero self-intersections, open contours, or overlapping lines: 1. Outer Profile Chain (Right Half, in mm): Connect the following points in order: (0, 0) to (30, 0) to (48, 22) to (37, 74) to (15, 100) to (9, 100) to (27, 70) to (24, 38) to (0, 38). Apply tangent sketch fillets to the vertices: R14 mm at (48, 22), R15 mm at (37, 74), R2 mm at (15, 100) and (9, 100), R20 mm at (27, 70), and R3 mm at (24, 38). 2. Bottom Internal Slot Chain (Right Half, in mm): Connect the following points in order: (0, 10) to (26, 10) to (32, 20) to (25, 29) to (0, 29). Apply tangent sketch fillets: R6 mm at (32, 20) and R6 mm at (25, 29). 3. Side Flexure Cutout Loop (Right Half, in mm): Create a closed 4-sided polygon connecting: (29, 53) to (29, 33) to (38, 24) to (41, 42) and back to (29, 53). Apply R5 mm tangent fillets to all four corners of this closed loop. 4. Mirror & Extrude: Mirror all three sketch groups across the vertical centerline X = 0 (do not create vertical dividing lines along X = 0). Verify that the resulting profile consists of one closed outer loop and three closed internal cutouts (one bottom horizontal slot and two symmetrical side pockets), then extrude cleanly to 8 mm.

Parameters

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.
