# Identify an [[OSAT]] that you would like to design to be a 3D printable technology
# Make sure someone else has not already done it
see the existing designs [[:Category:OSAT_3D-Printable_Designs|here]].# Reserve your OSAT by signature tagging with <nowiki> ~~~~ </nowiki> 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.
# Design 3D printable components with <u>ONLY</u> OS CAD packages (e.g. OpenSCAD, FreeCAD, or Blender)
# Create a Appropedia page for your project. (Easiest way to create a page is to search for the name of it and then click on the red link)# Include the following on the page
, directions, explanation of what it is and a price estimate for a commercial equivalent) # Print component and bring to class # Add picture and link to your project page in gallery below.
Copy the wiki markup below to your page to use as a template
=Title of the device or system =
# 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?

Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use [[ Category: Water]] . Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in <nowiki>[[Category:How tos]],[[Category:Electricity]], [[Category:Electric lighting]].</nowiki>
