Lattice structured Connecting Rod

The original models were downloaded from here: https://grabcad.com/library/crankshaft-and-piston-assembly-4
These models imported into nTop to apply different TPMS lattice sttuctures (Gyroid, Diamnd, Lidinoid, Split-P) in all these connecting rods.
These models can only printed by 3D Printing.
