Where each $95.00 sale goes
Filament, power, your time $9.29Marketplace fees $5.20Left from this sale $35.51
One sale ties up the printer for about 8.5 hours. $35.51 ÷ 8.5 h = $4.18 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, my estimate
Why it might fail
- No major warning found, test small first
Be aware before you sell
Paid DIY file sets exist, so read their terms before selling finished boxes built from them. Fanatec and Logitech names should only state compatibility; established rig brands are the commercial competition. 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
Rig owners already pay high prices for simple printed mounts, so a plastic-only mount has strong margin. It works by starting with mounts for popular wheelbases, and fails if you add electronics and take on support and warranty.
