Smart humor for engineers, caffeine addicts, and creative minds.

I’m John Cummings, founder of JAC3D, where creativity meets clarity. After around 20 years in a strategic marketing and business development role for semiconductors used in power electronics, I discovered a passion for translating complex technical ideas into content that anyone can understand. That same skill now drives JAC3D — a brand built on clever, conversation-starting designs that blend engineering humor, pop culture, and real-world experience. Each mug, shirt, and gift is crafted to connect people through smart storytelling, authenticity, and a touch of wit. My goal is to make JAC3D a place where innovation and laughter intersect — one design, one smile, and one cup of coffee at a time.
