Your broken part, rebuilt and printed.

Can't buy a replacement anymore? Mail me the broken piece. I scan it or measure it, rebuild it in CAD, and print a new one, often stronger than the original. You approve a dimensioned proof before anything gets printed.

Works from anywhere you can ship a package.

How it works

Five steps from broken to back in service

  1. STEP 1

    Tell me about it

    Send photos and a short description through the quote form. I'll let you know if it's a good fit and what it'll likely cost.

  2. STEP 2

    Ship the part

    Once you accept the quote, I'll send you the address. Mail the broken piece, all the fragments, and the part it mates with if you can spare it.

  3. STEP 3

    Scan & model

    I 3D scan and measure the part, then rebuild it as a clean CAD model, fixing the weak spot that failed.

  4. STEP 4

    You approve the proof

    You get a rendered image with the key measurements. Nothing prints until you say it's right. Payment is due when you approve.

  5. STEP 5

    Print & ship back

    I print it, check the fit against your original, and ship the new part back with the old one.

The proof

You see the measurements before I print anything

Every job gets a proof: a rendered image of the new model with its critical dimensions labeled in millimeters, like the drawing above. Hold it up against your machine, check it with a ruler or calipers, and reply with an approval or changes.

What the proof shows

  • Overall size and the dimensions that matter for fit
  • Hole and slot sizes, positions and thread specs
  • Any changes I made, such as a thicker wall where the original cracked
  • The material and color I plan to print in

Revisions to the model before printing are part of the job. A change you request after approving the proof may be billed as a reprint.

Materials

Printed in the material the job needs

I'll recommend a material based on where the part lives and what it does. You can always ask for something different.

MaterialGood forNotes
PLAIndoor trim, covers, knobs, fit test piecesStiff and accurate. Softens in hot cars and near heat.
PETGGeneral replacement parts, brackets, clipsTougher than PLA, handles moisture and mild heat.
ASAOutdoor parts, anything in the sunUV resistant, holds up to weather.
Carbon fiber filamentLoad-bearing brackets, mounts, gears, parts that were originally metalChopped carbon fiber makes the part very stiff and heat resistant. Can replace many light-duty aluminum parts.
Glass fiber filamentStrong parts that take impacts or vibration, hot locationsGlass fiber adds strength and toughness, with a little more give than carbon fiber. Another option for replacing aluminum parts.
ResinSmall, detailed parts with fine featuresVery smooth surface and fine detail. More brittle than filament.
Shipping your part

How to send it

  1. Fill out the quote form first. Once we agree on the job, I'll email you the address.
  2. Put every broken piece in a zip bag, even the tiny ones. Fracture edges help me rebuild the original shape.
  3. If you can, include the part it attaches to, or photos of it with a ruler in frame.
  4. Wrap it in bubble wrap and pack it in a box, not an envelope.
  5. Put a note inside with your name, email and quote number.
When to ship

Wait for the go-ahead

Please don't ship anything yet. Once we've talked through your part and you've accepted the quote, I'll email you the shipping address.

Shipping your finished part to you is included in your quote. Your original comes back in the same box unless you tell me to recycle it.

Questions

Common questions

What kinds of parts can you make?

Plastic parts that broke or wore out: appliance clips and knobs, vehicle trim and brackets, equipment covers, hinges, gears, battery doors and similar. If the original was metal, I can often design a printed part that does the job. Ask first.

Can I just send photos instead of the part?

Sometimes. Simple parts can work from good photos with a ruler in frame and a few caliper measurements. For anything that has to fit precisely, having the physical part gives the best result.

What if it's broken into pieces or missing a chunk?

Send what you have. I can rebuild missing sections from the surrounding geometry and the part it mates with.

How long does it take?

Typically 1–2 weeks after the part arrives, plus however long the proof approval takes on your end.

How much does it cost?

It depends on how complex the part is. Modeling is most of the cost; printing is usually small. Jobs start at $55.

From your photos I'll give you an estimate. Once the part arrives and I've measured it, I'll confirm the price before I start any work. If the price changes and you'd rather not go ahead, I'll mail your original part back and you pay the postage. Payment is due when you approve the proof, before anything prints.

Can I order more copies later?

Yes. I keep your model on file, so reorders skip the design step and cost only the printing and shipping.

Can I get the CAD or STL file?

No, I don't sell or share the design files. Your model stays on file with me, so whenever you need another copy or a small change, just ask. Reorders skip the design step.
