Make things worth keeping.
A solo design and fabrication studio based in the UK. Precision 3D printing, engineering consultation, and objects built to last.
Three ways to work together
Project management, mechanical design, and process advisory for makers, startups, and product teams.
Bring a file or an idea. I handle the rest — from prototypes to production-quality parts.
A curated range of 3D printed objects, designed and made in-house. Opening soon — join the list.
Built on process. Driven by craft.
I'm Rob — a mechanical and manufacturing process engineer turned full-time maker. RJ Design operates across design, fabrication, and consulting, with a focus on work that's made properly and built to outlast the trend cycle.
I design puzzles, mechanisms and kinetic sculptures. Everything I put out is worth keeping.

Currently taking enquiries
Every project starts with a conversation. Whether you have a detailed brief or just an early idea, get in touch and we'll figure out whether it's a fit.
Start a conversationCommission work
Have something specific you want designed or fabricated? Send a brief — describe what you're after, what it needs to do, and any constraints.
Send a briefCustom 3D Printing
Got a file? Got an idea? I offer precision FDM printing as a service — prototypes, functional parts, display pieces, and everything in between.
Drop a message with your file, a sketch, or a description of what you need. STL, STEP, or just an idea — all welcome.
You'll get a quote covering material, time, and any finishing. Pricing varies — get in touch for an estimate.
The job is printed, checked, and photographed. Any issues are flagged before the part leaves the studio.
Posted via tracked delivery, or collection by arrangement. Packed properly — not thrown in a box.
Pricing and turnaround depend on size, material, and complexity.
