From Broken to Brand New: How We 3D Print Replacement Parts

Appliances and furniture rarely break in convenient ways. It's almost never the whole thing — it's one small plastic part: a fridge shelf clip, a discontinued oven knob, a bracket that's been out of production for a decade. Replacing the whole appliance over one broken clip feels wasteful, and often the part simply isn't sold separately anymore. That's the gap we spend a lot of our time filling.

It starts with the broken piece itself

You don't need a 3D file or technical drawing to get started — just the original part, or what's left of it. Drop it off at our Cape Town studio or courier it to us. Our modelling team measures it, studies how it mounts and interacts with the surrounding assembly, and rebuilds it as a proper 3D model rather than just eyeballing a rough copy.

Why the material choice matters here

Replacement parts are almost always functional first — a knob needs to grip and turn, a clip needs to hold tension, a bracket needs to bear weight. That's why most of our replacement work goes out in PETG or ABS rather than PLA: we're matching the part to the job it has to do, not just the shape it needs to be. If you're curious how we make that call, we break it down in our guide to choosing a 3D printing material.

Getting the fit right

The most common failure mode for a 3D printed replacement part isn't the print — it's the fit. Discontinued parts often have subtle mounting details that are easy to miss from a quick glance: a slightly tapered peg, a specific screw boss depth, a snap-fit tolerance. We test-fit where possible and iterate before committing to a final production run, because a replacement part that doesn't seat properly isn't a replacement at all.

Worth trying before you replace it

If something in your home, car, or workshop has a broken plastic part holding it back, it's worth sending us a photo before you write the whole thing off. A surprising number of "irreplaceable" parts turn out to be a same-week fix. Message us on WhatsApp with what's broken and we'll tell you honestly whether it's a good candidate — or see the full range of things people bring us for more examples.
