About JAC3D

Get to know me

I’m John Cummings, founder of JAC3D, where creativity meets clarity. After more than 17 years in strategic marketing and business development at Texas Instruments, 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.
