Project Background
The purpose of the OSAT project is for me to improve upon another project that someone else has done.
Here are the original project and my improvement project side by side (my project is still in the STL file stage, not printed yet):
- OSAT Projects
-
Original Design.
-
My Design.

Abstract
- This project is done to create a better version of a tent stake that I found. My version has a better head to use a hammer on, it is twisty like the original, but it also has a point on the end of it so it can pierce the ground better and is able to twist in after that. This would be appropriate for ground that is firmer and harder to penetrate with a dull end, like the original design. I used OpenSCAD to design this tent stake. This use of open source technology and design helped me to understand OpenSCAD more completely as well as make it easy for anyone to open the OpenSCAD program and improve upon my design to continue to improve designs everywhere.

Bill of Materials
- Provide a full BOM -- Materials needed for fabrication of device and alternative materials if they are not available, prices/sources of non-printable parts
- Upload and link to all source files from open source CAD
- Upload and link to all STLs
Tools needed for fabrication of the OSAT
- Jellybox 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
- 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.
- Include print time estimate
- Include assembly time estimate
- Including drawings or pictures of the device at stage of assembly at minimum. (http://www.appropedia.org/Special:Upload)
- 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.
- Estimate your costs
- Find a commercial equivalent
- Calculate $ savings and % savings
References
- 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.

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 [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
