You’ve seen their awesome interchangeable iPhone covers before, and now we’re teaming up with Graft Concepts for a contest! Using three templates they provide, we want to see the most innovative backplates for an iPhone. The winner will receive $500 worth of printing from Shapeways and four iPhone cases from Graft Concepts.
From the guys at Graft Concepts:

When we designed the Leverage i5, we had 3D printing in mind. We specifically made the thickness of the backplate to match the tolerances of popular 3D printing materials. We wanted anybody to be able to design and print backplates for our Leverage i5 case. So here we are, releasing 3D fies of our backplates free of charge. Anyone may share, modify and make commercial use of the work, all we ask is that you drop a link in your file description to our site at: http://www.graftconcepts.comThat means anybody can create a backplate that fits on our Leverage i5 case. We are really excited with this experiment and can’t wait to see what innovative ideas people come up with!

How to Enter 
  • Download the template STL files from the Graft Concepts Shapeways Shop. You have three to choose from: flat, credit card and headphone wrap.
  • Design a backplate for the Leverage i5
  • Upload your design and tag it with “GraftConcepts” (one word)
  • Put a link to somewhere in your description so that people know the backplate works in conjunction with an existing product.
  • Save and be sure to check “Display to public” so that we can see it
  • The winner gets $500 worth of printing from Shapeways and four iPhone cases with two credit card holder backplates from Graft Concepts.
  • A runner-up will receive two cases of their choice and a credit card holder backplate from Graft Concepts.
Getting Started with the Template files
Flat: the plain backplate 3D file of the backplate that comes with all Graft Concepts Leverage i5 cases. Use this a template for building your own backplate.

Credit Card Holder: This is the same as the injection molded backplate we are selling. The current file allows for carrying 4 credit cards. You can modify it to carry more or fewer cards.
Headphone wrap: this backplate allows the headphone cord to be neatly organized. You can adjust the size to match the particular model of headphones you use.

You can download the files for free, or if you’d like the physical 3D prints, simply purchase them through Shapeways. Make something that would add an extra function to the case, there is a sample wallet replacement and headphone cord wrap as examples of utility backplates. Check out this video to see how the case works.

Judging will be done by employees of Shapeways and Graft Concepts using criteria based on a combination of uniqueness and/or utility. Number of “Likes”, “Tweets” and “Pins” will also be taken into consideration, especially for those close calls. Contestants must provide a title of their design and a brief description of how it functions in order to help in judging.

You have until June 30th so get designing! We can’t wait to see what you create!
