Bespoke parts, designed and built by one obsessed maker.

I’m Joe Kelly. I design, manufacture, sell, and personally support every single JK3D product myself, from my workshop in Salida, Colorado. When you buy here, you’re buying direct from the person who made it — no factory, no middleman, and no AI in any of the design or work.

As of 2026, JK3D has shipped thousands of orders to 60 countries — with exactly zero returns for product-satisfaction issues. I believe customer service is what separates a real business from the run-of-the-mill, and I stand behind everything with the brand on it.

Why I do this

I’m an engineer and a lifelong geek who fell hard for 3D CAD design and additive manufacturing. I’m also an avid motorcyclist, backpacker, skier, and photographer — so most of what I design solves a real problem I’ve hit myself in those pursuits. My goal is simple: make the gear you use work better, fit right, and last. JK3D.us is operated as a business unit under Wave Particle Industries LLC.

The short version of how I got here

  • 2014–2016 — Started designing my own ultralight photography and backpacking parts.
  • 2017–2019 — Bought my first 3D printer, then designed and built my own high-end IDEX printer from scratch (read about it here).
  • 2020 — Manufactured thousands of PPE components during COVID, and began designing motorcycle parts starting with my Yamaha Tracer 900GT.
  • 2021 — Launched JK3D.us to get these designs into more riders’ and makers’ hands. (An early favorite still for sale: Bigfeet.)
  • Today — A dedicated design-and-fabrication workshop, contracted design work for other companies, and expanding into metalwork. I chronicle the journey on my blog, joekelly.co.
