Where each $22.50 sale goes
Filament, power, your time $4.66Marketplace fees $1.40Left from this sale $3.94
One sale ties up the printer for about 1.75 hours. $3.94 ÷ 1.75 h = $2.25 per print hour.
At the mid price, if it sells. Shipping not included.
Why it can work
- Low brand or licence risk if the design is your own
Why it might fail
- Thin public evidence, so treat these numbers with care
Be aware before you sell
MakerWorld terms on one result restrict sharing and selling printed versions, so check each file before selling. Numbers and names are low risk, though dog-breed files belong to their designers. Etsy asks for your own original design, so a licensed file may not qualify.
How to get a file you may sell
- Make your own. Tinkercad is free and enough for simple shapes.
- Buy a commercial licence. Many designers on Cults3D, MyMiniFactory and Etsy sell one. Read what it allows.
- Use open licences. CC0 and CC BY allow selling prints. NC does not. Filter by licence on Printables or MakerWorld and keep a screenshot.

Our take
Only one printed price turned up; the high end is a non-printed comparable, so the true range is unclear. It works in UV-stable outdoor material and fails if PLA signs warp in the sun.
