Description
Articulated eight-arm octopus, modeled from published dimensions. Overall 152 x 152 x 25 mm. Key dimensions: arms 8; segments per arm 2; pin diameter 3.6 mm; hole diameter 4.3 mm; radial clearance 0.4 mm; vertical clearance 0.4 mm; print in place true. Original solid CAD modeled from scratch. Closed meshes and digital clearances are checked; physical printing and load/flow performance have not been tested. Use millimeter units for STL. Original rounded octopus head and eight two-segment tentacles with side-to-side captive-pin articulation. Sixteen moving segments are separate closed solids. Print the supplied flat arrangement with joint supports disabled. Head overhangs and short joint bridges depend on printer settings; 0.35 mm joint gaps are a starting allowance, not a guarantee of free movement on every printer. Watertight STL mesh in millimeters, ready to slice; printed performance is untested. Export to 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.
