For this 3D Project Challenge brought to you by 3dcreationsystems.com we are asking you to design or modify a jack o' lantern in 3D. Don't worry you've never done any 3D design at all before. We have instructions for how to make your own jack o' lantern as well as templates that you can modify.

The Instructable that covers the design of our jack o' lantern is here. Follow along with the instructions or go your own way!

Once again, there are two different ways to enter:

1) Design your own jack o' lantern in any CAD program you want
2) Modify this file on 123D

Once your design you can enter it as a photo Instructable with a couple of renders of the results or make a full step-by-step Instructable. We can't wait to see what it looks like!

Multiple entries are accepted, but each entrant can only win one prize. Contest is open to entries from US, Canada [excluding Quebec], UK, China, Belgium, the Netherlands, Australia, Colombia, Germany, Switzerland, Norway, India, New Zealand, and Denmark. The Contest begins at 12:00 a.m. Pacific Standard Time (PT), September 20. Contest closes for entries at 11:59pm PT, October 21.
