Description
Helical coupling, 8 to 8 mm, modeled from published dimensions. Overall 25 x 25 x 30 mm. Key dimensions: bore 1 8 mm; bore 2 8 mm; outside diameter 25 mm; length 30 mm; bore transition z 15 mm; hub shaft engagement 8 mm; slit pitch 3.2 mm; slit turns 3; slit axial width 0.7 mm; clamp screws 2 x M3, cylindrical thread envelopes. Original parametric helical-beam coupling. The continuous 3-turn cut joins two slotted clamp hubs in one solid; declared dimensions are library design choices, not vendor specifications. The model is shown unstressed. Beam strength, torsional stiffness, misalignment capacity and fatigue life have not been calculated. Thread forms and tightening deformation are omitted. Shaft insertion should remain within the 8 mm end hubs. Exact solid STEP geometry in millimeters, opens in any CAD system. Export to STL, OBJ, GLB and other formats from the viewer. Nominal dimensions for layout, fit checks and visualization; they do not establish a manufacturing tolerance class, load rating or standards certification. Original Innerscene model, released CC0.
