Design Guidelines



Dear Designers,

In order to create objects loved by the Maker community, here are a few tips to help you design 3D printable objects.



1. Design your objects in millimeters (1inch = 25.4mm) so that Makers can easily compare designs, printing time and cost estimation.
2. Export your design in STL format, the most common file for 3D objects in the world.
3. Design your objects for conventional plastic 3D printers (click here to see a list of available plastic 3D printers)
4. Limit your objects to a maximum size of 300x300x300mm (11.8 x 11.8 x 11.8 inches).
5. Printing time is displayed at the top right corner of your object page. Try to reduce printing time so that Makers can enjoy your best creations faster than ever. Keep in mind that if you double the size of a design, it will take 8x more time to be printed.
6. Center your designs along the positive z-axis.
7. Orient your objects, as it should be positioned on the 3D printer building plate. The building plate is usually at z=0 in the x-y plane. In consequence, Makers can start printing without any additional operations.
8. Avoid roofs in your designs whenever possible. Some 3D printers have hard time with those. If you can’t avoid these, please add structural supports for printing purposes.
9. Set a minimum gap of 0.3 mm (0.012 inches) between walls so that the resulted object will be functional the first time.
10. Write short and precise descriptions so that Makers can find your objects more easily. Please include the optimal printer parameters.
11. All walls should be minimum 1mm (0.254 inches) thick.
12. Keep in mind that most plastic 3D printers use either PLA or ABS polymers. These polymers have limited mechanical strength. Keep in mind that a plastic cylinder with a section of 10 mm2 (0.015 inches2) can support a maximum charge of 6 kg (12 pounds) in traction. If you divide the section by 2, the maximum charge supported is also divided by 2.
13. Please don’t cross the line: don’t upload any objects that are intended to hurt someone (click here to understand our takedown policy). If you have any questions, please don’t hesitate to write us at support@cuboyo.com
