Show us the part and what it fits
The broken piece is only part of the picture. The shaft a knob fits, the holes a bracket lines up with or the space around a mount can determine whether a replacement is useful. Keep any remaining pieces and photograph the assembly before removing information you may need.
- Send photos from several angles, with known dimensions.
- Include the original or its remaining pieces if available.
- Show the mating surfaces and any fasteners or neighbouring parts.
- Explain what failed and whether the part was exposed to heat, sun, moisture, movement or impact.
Rebuild the shape with the failure in mind
We measure what is left and model the part in CAD. Where it makes sense, the design can address the feature that failed rather than simply copying the break. Missing or worn features may need more information before dimensions can be settled.
A prototype can help check fit against the actual assembly. Mark which areas interfere or feel loose and identify the version you tried before asking for a revision.
Choose material for the replacement job
An indoor knob, outdoor mount and flexible grip have different needs. PLA may suit an indoor model or fit check, while PETG, ASA, TPU or nylon may be candidates for other uses. Selection depends on the actual conditions and geometry.
Matching the colour or shape does not establish equivalent performance to the original. Tell us about the application and any known material information so we can discuss the limits as well as the options.
Some parts need a different conversation
Not every original part should be replaced with a printed one. Safety-critical applications, including braking systems, require case-by-case discussion. A photo alone is not enough to establish suitability.
If the requirement is tight-tolerance metal or a process printing cannot serve well, we will say so. No universal fit, lifetime or safety guarantee is made for a replacement based only on its appearance.
Get the design and quote clear first
CAD time and printing are discussed in the written quote, with design and quote approval before making the part. One-offs are welcome. Timing depends on the design, material and queue, so include your deadline.
Prairie Prototyping is based in Saskatoon, Saskatchewan. Pick up locally or have the finished part shipped within Canada. Send what you have, even if the original CAD file no longer exists.
