LEGO (R) Compatible T72 Gear Ver.2

grabcad

The T72 Gear, designed using DesignSpark Mechanical (ver.2015.0), is LEGO compatible. To enhance its functionality, I corrected the previous model's gear shape. Key specifications include Module m=1, Pressure Angle a=20 deg, Pitch Diameter d=72 mm, Addendum (Outside) Diameter 74 mm (d+m x 2), Root Diameter 69.5 mm (d-m x 2.5), and Base Diameter 67.66 mm (d*cos(a)). Although 'd + m x 1.5' is suggested for a better fit, it remains a LEGO gear.
