The best way to get a one-off part made: five routes compared
Buyers pay no fee. Payment is held by our payment partner until you confirm delivery.
Side by side
| Route | Best when | You need | How you pay | Watch for |
|---|---|---|---|---|
| Online manufacturing service (e.g. Xometry, Craftcloud, SendCutSend) | You have a finished file and want an instant price | A CAD or 3D file, sometimes a drawing | Upfront at checkout; business credit terms at some | Minimums and regional limits, e.g. Xometry Europe €30; SendCutSend ships to the US and Canada only |
| Etsy custom order | A shop already makes something close to what you want | A message to the shop | Buy a private listing; Etsy Purchase Protection applies | 3D-printed and laser-cut items must be the seller's original design |
| Local machine shop | Precision metal parts, tight tolerances, a drawing | Usually a drawing; ask the shop | Set by the shop | Setup cost dominates on quantity one |
| Makerspace | You want to make it yourself and learn the machine | Membership and tool training | Membership fee plus your materials | Training time; not every space has every machine |
| Maker marketplace (The Spool List) | No file, a repair, a prop, or a job needing finishing; 17 disciplines | Photos, measurements or a file | Upfront; held by our payment partner (Stripe) until you confirm delivery; no buyer fee | You wait for quotes rather than getting an instant price |
If you have a finished CAD file
Use an online manufacturing service for an instant price and checkout.
Xometry quotes CNC, sheet metal, 3D printing and more from an uploaded file and lists ISO and AS9100D certifications and ITAR registration (Xometry FAQ); in Europe, orders must be at least €30 (Xometry Europe). Craftcloud compares 3D printing prices from partner manufacturers with no minimum order value (Craftcloud). SendCutSend cuts sheet parts from DXF-style files, ships free in the US on orders of $39 or more, and ships only to the US and Canada (SendCutSend).
These are the fastest route when the file is right. If the file is wrong, they make exactly what the file says.
If you only have a broken part, photos or a sketch
Choose someone who will measure, ask questions and quote: a local shop or a maker marketplace.
On quantity one, setup is most of the cost. Make: magazine's guide to hiring a machine shop puts it plainly: "The cost to set up a machine to make your part is divided by the number of parts you're making" (Make:). The same guide advises loosening tolerances and surface finish wherever the part allows, because both drive cost.
On The Spool List you post the job free with photos and measurements, verified makers quote, and you choose. Many repairs don't need a machine shop: a printed nylon knob or a laser-cut acrylic bracket can do the job. Payment is held by our payment partner, Stripe, until you confirm delivery (returns and disputes), and buyers pay no fee (pricing).
If the part needs certification or a production run
Go to a certified supplier.
Aerospace, medical and automotive parts, ITAR-controlled work and anything needing inspection paperwork belong with a supplier that holds those certifications. Xometry, for example, offers CMM inspection reports and first article inspection to AS9102 as add-ons (Xometry FAQ). The Spool List doesn't hold manufacturing certifications at platform level.
If you want to make it yourself
Join a makerspace, and budget time for training.
Membership prices vary widely: published examples run from $15 a month (College of Southern Maryland) to $120–$240 a month at Maker Works in Ann Arbor, which requires a tool training class before CNC machines, laser cutters, 3D printers and welders (Maker Works).
Frequently asked questions
How do I get a part made without a CAD file?
Use a route that quotes from a description: a local shop, or a maker marketplace like The Spool List where you post photos and measurements. Instant-quote services need a file.
Why is one part so expensive?
Setup. The cost of setting up a machine is divided by the number of parts, so on quantity one the whole setup lands on a single part.
Is 3D printing good enough for a replacement part?
Often, for knobs, clips, covers and brackets that aren't heavily loaded. For hot, high-load or wear parts, ask about metal or a tougher material.
Which route is cheapest?
It depends on the part, material, quantity and shipping. Get quotes from at least two routes for the same job.
Which route is fastest?
With a correct file, online services publish lead times by process. Without a file, the fastest route is usually whoever can measure and quote first.
