LEGO - Technic Tread Sprocket Wheel Small (#57520)

thingiverse

This is a simplified version of LEGO part #57520: Technic Tread Sprocket Wheel Small, featuring six sprockets that fit seamlessly into large track treads like #57518. I consulted https://www.thingiverse.com/thing:2859595 as a reference to verify dimensions and clearances before creating the part entirely from scratch in Rhino3D (v6). The printing parameters were set at 0.15mm layer height and 50% infill, necessitating the use of supports. It's worth noting that the center axle is intentionally oversized by 0.1mm in each direction to accommodate printer slop. However, tolerances may vary significantly from one printer to another.
