Open Source 3-D Printing/OSAT projects

This is a project that supports the course Open Source 3-D Printing

=Assignment=
 * 1) Identify an open source appropriate technology (OSAT) that you would like to design to be a 3D printable technology
 * 2) Make sure someone else has not already done it : existing designs here. (You can choose to do a major improvement on past design)
 * 3) Reserve your OSAT by signature tagging with ~ next to the OSAT on the list generated by the Appropedia community: Requests for 3-D printable open source appropriate technology. You can add your own ideas to the list, more than one of you can tackle the same tech in a different way, you may improve upon existing designs if you do so in a significant way. Double check someone else has not already done a better job - use http://yeggi.com
 * 4) Design 3D printable components with ONLY OS CAD packages (e.g. Blender or OpenSCAD or FreeCAD)  for FreeCAD put on https://www.youmagine.com/ and link back to it on Appropedia.
 * 5) Create an Appropedia page for your project.
 * 6) Include the following sections on your page using the template below (copy and paste wiki markup into your page)
 * 7) Add picture and link to your project page in gallery below.
 * 8) Print component and bring to class

=Grading=
 * 20% Print quality
 * 30% Documentation
 * 25% Design (design for printing, plastic minimization)
 * 25% Function - Is it OSAT? Does it work?

Automatic reductions: -50% no source or the use of non-OS software -10% per day for late

=Gallery= Add your image and link the gallery below in a single line after the last one in the list

=Template For use in Appropedia - copy and paste all wiki markup below and paste on new page on Appropedia=

Copy the wiki markup below to your page to use as a template (note all red text, images, and videos will show in Appropedia)

Title of the device or system
Project developed by [your name linked to your user account]

You can help Appropedia by contributing to the next step in this OSAT's status.

Abstract

 * 1) Paragraph description of the OSAT - why is it Appropriate? What need does it fulfil? Are there case studies you have found of a technology being used successfully?
 * 2) Picture of completed print using your printer

Bill of Materials

 * 1) Provide a full BOM -- Materials needed for fabrication of device and alternative materials if they are not available, prices/sources of non-printable parts
 * 2) Upload and link to all source files from open source CAD
 * 3) Upload and link to all STLs

Tools needed for fabrication of the OSAT

 * 1)  MOST Delta RepRap or similar RepRap 3-D printer

Skills and Knowledge Necessary to Make the OSAT

 * If you used special skill – link to relevant wikipedia or wikiversity articles/courses

Technical Specifications and Assembly Instructions

 * 1) Provide directions for print/assembly - be detailed enough in your “how to” to ensure that someone could construct the device from your description. Consider the elegance of IKEA like instructions.
 * 2) Include print time estimate
 * 3) Include assembly time estimate
 * 4) Including drawings or pictures of the device at stage of assembly at minimum. (http://www.appropedia.org/Special:Upload)
 * 5) Consider video if appropriate

Common Problems and Solutions

 * Include common mistakes/problems to avoid in building your OSAT and how to overcome them

Cost savings

 * If your solution is not a low cost one then it is not really appropriate.
 * 1) Estimate your costs
 * 2) Find a commercial equivalent
 * 3) Calculate $ savings and % savings

Benefited Internet Communities

 * Name and add links to at least 5 using single brackets around [url name]
