Make a project using any kind of CNC machine or 3D printer.

Some examples of common CNC operated machines you could use: laser-cutters, plasma cutters and water jets, mills and routers, and even desktop craft cutting machines.

3D printers are technically CNC machines, so all projects that use any 3D printed materials are eligible as well.

Document your project in an excellent Instructable and you could win!

There are two bonus Judges prizes:

- Our favorite project designed using Tinkercad

- Our favorite project designed using Fusion 360

Use Tinkercad or Fusion 360 in the design and creation of your real-life physical project, and you'll be eligible for the special Judges prizes.

Upon publishing your Instructable you'll see checkboxes for open contests. Select CNC and 3D Printing Contest. If you have entries currently eligible for entry, it will also show up by clicking "Enter this Contest" on the right side of this page.


Entries are accepted by Instructables staff within one business day Monday - Friday. What matters is the submission time, not acceptance time.
