ASTM D6641 CLC Fixture (Exploded Parts)

Create a 3D CAD assembly of an ASTM D6641 Combined Loading Compression (CLC) test fixture, in inches, stainless steel, export as STEP. ENVELOPE: 4.2" (X) x 2.1" (Y) x 5.5" (Z). Z is the load axis, origin at center. BODIES (separate solids): - 4 rectangular blocks, each 2.1" x 2.1" x 2.5" [assumed height]. Two form an upper pair and two a lower pair, mirrored about Z = 0. - 0.5" vertical gap between upper and lower pairs (gage section at Z = 0). - 0.5" wide vertical slot between the left and right block of each pair, running full depth in Y, with flat ground faces to hold a flat specimen (up to 1" wide, 0.5" thick, 5.5" long). - 3 bolts per pair on the +X face (12 total across both sides), 1/4"-20 socket head cap screws [assumed], with counterbored clearance holes in the near blocks and tapped holes in the far blocks. - 2 vertical linear bearing rods, 0.5" dia x ~4.5" long [assumed], running through bores in the upper and lower blocks to keep the pairs aligned. Concentric ring bore (0.75" outer, 0.5" inner) visible on the top face of each upper block. - Circular extensometer recess, ~1" dia x 0.5" deep [assumed], on the -Y face at the upper/lower gap, centered at Z = 0, showing as semicircular notches on the facing block edges. - Specimen as a separate semi-transparent body, 5.5 x 1.0 x 0.25", centered in the slot. DETAILS: Flat 4.2" x 2.1" top and bottom faces for platen mounting. 0.02" edge chamfers. Brushed stainless finish. NAME BODIES: Block_Upper_Left/Right, Block_Lower_Left/Right, Rod_Left/Right, Bolts, Specimen. OUTPUT: assembly plus exploded view and XZ section view.
