Plastics, plastics everywhere and so many projects to make. Up-cycle your recyclables or 3D print something completely new; as long as some type of plastic is your material of choice, you can enter the Plastics Contest!

Grab it, shape it, move it, make it and you could win a Printrbot Smalls, Dremel 21-Piece Multipurpose Rotary Tool Kit, or Dremel Micro Rotary Tool Kit! There’s not much this versatile material can’t do so get out there and produce projects from plastic.

The Plastics Contest is closed.

Upon publishing your Instructable you'll see checkboxes for open contests. Select Plastics 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.
