Gear Teeth Anatomy – Perfect Pitch Edition Tri-Blend Shirt

Gear Teeth Anatomy – Perfect Pitch" is the ultimate mashup of engineering precision and geeky humor. This t-shirt features a clean 3D line diagram of two gear teeth with all the essential parts labeled — addendum, dedendum, pitch circle, and more — just like in a real technical drawing. The phrase “PERFECT PITCH” ties it all together with a clever nod to the gear tooth pitch that mechanical engineers know and love. Whether you’re a mechanical engineer, machinist, maker, or just someone who loves clever STEM humor, this shirt is a conversation starter that turns mechanical theory into wearable art. Printed in crisp white (with yellow centerlines) on dark shirts for maximum contrast, it’s as precise as your favorite set of calipers.
