T-slot 20 x 40 x 250 mm
T-slot 20 x 40 x 250 mm, modeled from published dimensions. Overall 40 x 20 x 250 mm. Key dimensions: width 40 mm; height 20 mm; length 250 mm; slot pitch 20 mm; slot throat 5 mm; core bore 4.3 mm; profile series I-type slot 5. Nominal outer envelope, slot pitch/throat and core holes follow the cited drawings. Length is a selected 250 mm cut. Core holes are untapped. T-slot geometry follows the I-type slot-5 profile, not the visually similar slot-6 or slot-8 systems. Undimensioned internal webs, center cavities and small corner radii are reconstructed approximations. Do not use the mesh to derive section stiffness, supplier mass or unlisted mating tolerances. 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.
