Where each $15.00 sale goes
Filament, power, your time $4.91Marketplace fees $1.54Left from this sale $5.04
One sale ties up the printer for about 2.2 hours. $5.04 ÷ 2.2 h = $2.29 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
- Seasonal demand: Christmas gifting, by judgement
Why it might fail
- Thin public evidence, so treat these numbers with care
Be aware before you sell
Check the terms on each WDT and funnel file, and on any stand design, since these were not confirmed. Machine brands such as Breville should appear only as fit statements. 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
Buyers spend freely and prints are small, but only one clean USD price was seen, and the upper range is in Canadian dollars, so the field shows that single value. Food contact is limited to dry grounds, which suits PLA for rakes, while funnels near hot grounds or steam need PETG and a stated fit per portafilter size.
