How to price 3D printed keychains
Keychains are small, fast and cheap in material, so per-unit labor, packaging and marketplace fees decide whether a price works.
Typical material use
5–15 g
Typical print time
0.3–1 h
Common materials
PLA, PETG
Hands-on time
2–5 min each
Step 1: work out your real cost
The calculator is preset for a typical keychain. Change it to your slicer's numbers.
Estimated cost per print
$1.67
- Material
- $0.20
- Electricity
- $0.01
- Printer wear
- $0.07
- Labor
- $1.33
- Failed-print buffer
- $0.05
An estimate from the numbers you enter. It leaves out packaging, shipping, marketplace fees and tax.
What drives the cost
- The hardware (split ring, chain) often costs more than the plastic.
- Printing a full plate at once spreads printer time across many units.
- Personalized names add design minutes per order.
Costs the calculator leaves out
- Rings and chains
- Small bags or backing cards
- Postage for flat mail vs. parcel
Step 2: turn cost into a price
A simple method: price = (cost + fixed fees) ÷ (1 − fee % − margin %). Using the example print cost of $1.67, plus about $1.50 for extras, a 10% marketplace and payment fee and a $0.45 fixed fee gives:
| Target margin | Price that covers it |
|---|---|
| 10% | $4.52 |
| 20% | $5.17 |
| 30% | $6.03 |
Illustrative only. Use your marketplace's current fee schedule, shipping and tax. A price that covers cost is not a promise anyone will buy at it, so check demand and competing listings.
Pricing tips for keychains
- Price per unit and in bundles (for example 3 or 5) so the flat per-order fees are spread out.
- Personalization justifies a separate, higher price tier.
- Check that the fixed listing and transaction fees don't eat most of a low price.
