A keychain is about the smallest thing worth printing: 5 cm³, a few grams of PLA, minutes of machine time. Ordered alone it simply costs the shop's minimum charge. The interesting economics start with quantity — custom keychains for an event or a team print dozens to a plate, sharing one setup, so per-unit cost collapses toward raw material. The estimator defaults to a batch of five; push the quantity up and watch the per-order total barely move.

What drives the cost
Singles hit the minimum
No shop can profitably handle a $0.60 job. A single keychain is billed at the minimum charge — typically $5–$15 — regardless of its tiny material cost.
Plates, not pieces
A 220mm bed fits 20+ keychains in one print. One setup, one job, twenty units: that's how event batches get to a dollar or two per piece.
Color and personalization
Multi-color logos or per-name text add either filament swaps or per-unit slicing changes — small labor that matters at keychain price points.

Why does one keychain cost $10 but ten cost $12?
The $10 is the shop minimum covering fixed setup labor. Ten keychains share that same setup and print as one job, so you're only adding a little material and machine time.
How many keychains fit in one print job?
On a standard 220×220mm bed, typically 20–30 flat keychains. Larger beds or stacked printing push that higher, which keeps per-unit costs falling.
Can each keychain in a batch have a different name?
Yes — text is trivial to vary in the model. Expect a small per-variant fee since each unique piece needs its own file edit and slice.
