For buyers
At launch every project is free. Download any of them, or order a print. Paid files open later, once payouts to creators work.
Print files that fit what you have.
Find a design, set its sizes to your shelf, your drawer or your name, and take the file. No printer? Order the part and it is printed and shipped to you.
Three ways to get a part
Download it
Free projects download at once. Paid ones stay in your library, so you can download them again any time. Some creators let you pay what you want.
Make it fit
Projects with sliders let you change sizes the designer allows. The part is rebuilt in your browser before you download it.
Have it printed
Press Order a print, pick a colour, pay. A print farm makes the part and ships it. You see the price before you pay.
Change a size without a CAD program

Open a project
The sliders show what you may change and by how much.

Move the sliders
Holes stay round and walls stay the right thickness. It is the real part, made again.

Take it
Download STL, 3MF or STEP, open it in your slicer, or order the print.
More of what you pay reaches the designer
The designer pays the card fee and 1%. Of a $10 file:
Questions
Do I need an account?
Not to look, move sliders or download most free files; some creators ask for a free account first. Buying a file or a print asks for a sign-in so your library keeps it.
Does it work on a phone?
Yes. Projects, sliders, downloads and orders work on a phone. Designing your own parts needs a computer for now.
May I sell prints of what I download?
Each project shows its licence in plain words. Some allow selling prints, most do not. The project page says which.
