About Us

Our Story

3rd-Prints started with a simple idea: turn imagination into something you can hold. From custom cosplay props that light up the room to one-off replacement parts that keep your gear going, we specialize in custom 3D printing, cosplay builds, and small-batch parts—designed, printed, and finished with care in San Diego.

What We Make

  • Cosplay & Props: LED swords, emblems, armor accents, con-ready accessories. Explore our latest builds in the Cosplay Collection.
  • Custom Parts: Replacement clips, brackets, camera battery doors, prototypes. Need a quote? Start a Custom Print.
  • Gifts & Minis: Personalized pieces for games, holidays, and events. Browse everything in All Products.

How We Print (Quality You Can See)

We build for strength, fit, and finish. Our workflow includes dimensionally accurate slicing, tuned print profiles, and post-processing (sanding, priming, painting, and clear coats) so your part looks pro—not “just printed.”

Materials we trust: PLA, PETG, ABS, Nylon (PA), and Nylon-Carbon Fiber (PA-CF) for high-stress parts. Not sure what to choose? Our Material Guide explains when to use PETG vs PA-CF and more.

Our Mission & Values

  • Make It Accessible: Fast quotes, clear pricing, and file help for non-experts.
  • Built to Last: We recommend the right material and infill for your use case.
  • Creator-Friendly: We respect licenses and give proper attribution when applicable.
  • Fast Turnaround: Most standard projects ship in 1–3 business days after approval.

Meet the Maker

Hi—I’m Aaron, the maker behind 3rd-Prints. I’m a detail-obsessed builder who loves taking projects from “idea” to “in-hand.” Whether it’s a K-Pop Demon Hunters Rumi LED Sword or a precision battery door, I’ll help you choose materials, finishes, and timelines that fit your budget and your deadline.

How It Works

  1. Tell Us What You Need – Share photos, dimensions, or an STL. Start a Custom Print
  2. Approve Quote & Material – We recommend PLA/PETG/PA-CF based on strength, heat, and finish.
  3. Print, Finish, Deliver – Local pickup in San Diego or fast shipping.
