A better way to eat[edit | edit source]

Project developed by Forest.andresen (talk) 13:20, 25 April 2017 (PDT)

Add a status meter by copying the following templates (inside double curly brackets) into your page as you reach each step: status-design, status-prototype, status-deployed, status-model and status-verified....

Abstract[edit | edit source]

  1. Everyone eats, some eat with their hands, and some eat with utensils. This is a project focusing around bringing the best utensils to people worldwide, without the usual cost involved. This is the creation of a utensil that can be easily printed by a 3D printer anywhere around the world. Our wish at project spork is to enable all to have a clean and convenient eating experience. The better spork is made to be east to clean and to have significantly better cutting ability than any other spork/knife to date.

Bill of Materials[edit | edit source]

  1. Provide a full BOM -- This part needs only a 3D printer and a filament that is non toxic.
    1. Upload and link to all source files from open source CAD
    2. Upload and link to all STLs

Tools needed[edit | edit source]

  1. A 3D printer
  2. memory card
  3. computer
  4. various printer tools like tweezers

Skills and knowledge needed[edit | edit source]

  • You simply need to be able to download and the part and use a 3D Printer to make it.

Technical Specifications and Assembly Instructions[edit | edit source]

Common Problems and Solutions[edit | edit source]

  • I recommend including a brim to ensure the spork does not peel off the build plate while printing. This will need someone to chip off the brim when the spork comes out.
  • before loading the stl file into cura, I ran it through netfabb to make sure it would print. it turned out that it had some problems and was not a "water tight" shape yet.
  • I recommend sanding or polishing the parts of the utensil that will touch your mouth, otherwise the sharp areas can be uncomfortable or harm you.

Cost savings[edit | edit source]

  1. Printing this spork knife will cost under 20 cents. while buying a similar design on amazon will cost more than $8.
  2. https://www.amazon.com/dp/B0062MHSI2/ref=twister_B00OYSZG1W?_encoding=UTF8&psc=1
  3. In addition to the cost savings, this spork is a better design and specifically has a more effective knife. users can also customize the file before printing to make it the right shape and size for them and their diet.

References[edit | edit source]

  • The sources of information (e.g. engineering handbooks, journal articles, government documents, webpages, books, magazine articles etc.). References should use the <ref> </ref> and <references/> tags and can be in any format but should include all the information necessary for someone else to find the same information you did.
