What a Custom Car Part Quote Needs
Most custom part requests start with one photo and a sentence. That's enough to start. The more of the list below you send in the first message, the sooner I can tell you whether I can make it and what it costs.
What to send me
Year, make and model, or the machine it fits. Add the trim and engine if you know them. The same model year can use two different parts.
Photos of the area and the part it replaces. One wide shot so I can see where it sits, then close-ups of the mounting points, clips and anything it touches.
Rough dimensions, or the original part. A tape measure is enough to start. If you still have the old part, even a broken one, I can measure it or scan it.
Where it sits: underhood, interior or exterior. That decides the material more than anything else.
How many you need. One, a pair, or a small batch.
What it has to do. Hold a sensor, route air, cover a gap, take engine-bay heat. One sentence is fine.
What I won't make
I don't print anything in the exhaust or turbo heat path, or anything in steering, suspension or brakes. If your part is one of those, I'll tell you up front.
How the price works
Custom work is quoted per part, not per hour. Three things move the number: how much modeling the part takes, the material, and how many revision rounds it's likely to need. A flat bracket and a full intake tract are very different jobs.
You get the price and a delivery window before I start any CAD. The price doesn't move unless the scope does.
The terms
Quoted jobs of $200 or more start with a 50% deposit. The balance is due at pickup or delivery.
Jobs under $200 are paid in full when you order.
Quotes are good for 14 days.
Design work includes 2 rounds of revisions. Extra rounds are quoted in writing before I keep going.
If the job needs a sit-down design consultation, it's $25, credited in full toward the job if you book it.
I keep the CAD file I create. If you want the file too, a buyout is 50% of the design fee.
The full list is on Shop Policies. If a written quote and the policies ever disagree, the quote controls.
Fit checks
If the car can come to my shop in Washington, IL, the part gets test-fit on it before it leaves. If it can't, I build it to your measurements, and when the fit is tight a fit-check prototype comes first.
Materials
Under-hood parts are usually printed in PA6-GF glass-filled nylon, the same material family as OEM under-hood parts. A printed part is weaker than a molded one, mostly across the layers, so I make the walls thicker. Interior and trim parts are usually PETG or ABS. Flexible parts like grommets and boots are TPU. I print final parts on my enclosed Bambu Lab X1 Carbon. PA6-GF vs ABS and PETG, with the data-sheet numbers →
