The honest answer is "it depends," but four things do almost all of the work in getting from "it depends" to an actual number: material, process, size, and quantity.
Material and process
FDM in PETG or ASA is the cheapest route and covers most exterior trim — bumper pieces, covers, brackets. SLA resin costs more per gram but wins on fine detail: badges, switch bezels, anything with sharp lettering. SLS nylon sits at the top of the range and is worth it specifically when a part flexes or takes repeated mechanical load, like a clip or a handle.
Printing the wrong process for the job costs more in the long run than it saves up front — a badge in FDM will look soft, and a load-bearing clip in resin will crack.
Size and geometry
A small interior clip and a full diffuser lip are not the same job even in the same material. Larger parts take more material and more print time, obviously, but geometry matters too: a part with a lot of overhang needs support material that gets removed afterward, which adds labour on top of print time.
SHIPS 3–5 DAYS
The three-piece diffuser lip above is a useful example of both axes at once — it's a larger, multi-part exterior piece, and it's priced accordingly against a small interior clip a fraction of the size.
Quantity
Per-unit price drops fast between one part and a small batch, because setup and post-processing are largely fixed costs regardless of quantity. If you need forty of something, tell us up front — the per-part economics change enough that it's worth quoting as a batch from the start rather than as one part, forty times.
What doesn't change the price much
Colour, within a material's standard range, is close to free. Post-processing (bead blasting for texture, painting, clear coat) is the exception — that's real added labour and is priced separately.
