Abstract

The idea behind this OSAT is very simple and nothing groundbreaking. A simple tent stake. To some it may not seem important or essential in any way but those that have pitched a canvas style structure know how valuable they can be. A tent stake doesn't have to hold up just a tent, it can be an anchor for many different kinds of shelters. That is why I thought this would be an appropriate OSAT project. Tent stakes are something used all over the world. They could be used to pitch a tent on a camping trip or to secure a medical tent in a small foreign town. This also brings up the issue of design flexibility to meet all these different use cases. There are, in fact, many different designs and styles for tent stakes already in existence. They mainly vary based on material but the environment in which the stake will be used is the second biggest factor. The ground in which the stake will be lodged could include any mixture of soil, sand, gravel, mud, or roots. For my design I chose a very common style for plastic tent stakes but with some of my own personal changes from experience. I made the CAD model so that way it would print easily and the stresses common for a tent stake would not affect a 3D printed version.

  • The stake head is slightly larger than most so the user can easily push it into the ground.
  • The tip is sharp for cutting through roots and the shaft is strong to resist strain.
  • The hook provides a larger recess to ensure that the rope/string will not come out even if the stake pulls out of the ground slightly (a common occurrence).


Bill of Materials

  1. 3D Printer
  2. Tent Stake model
  3. PLA/ABS/or other appropriate filament
    1. Upload and link to all source files
    2. 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

Common Problems and Solutions

Stake Weakness

  • It is essential that the tent stake be printed near perfectly and with at least 20% fill to ensure proper strength

Cost savings

  1. Estimated costs

$0.25 per stake (purely the cost of the filament for printing)

  1. Find a commercial equivalent

$0.75 per stake http://www.rei.com/product/798883/coghlans-abs-tent-peg-6/?cm_mmc=cse_PLA-_-pla-_-7988830019&mr:trackingCode=3B8FEEF6-2847-DF11-BAA3-0019B9C043EB&mr:referralID=NA&mr:device=c&mr:adType=pla&mr:ad=64530460840&mr:keyword=&mr:match=&mr:filter=68532232480&msid=Fyt17WDq_dc%7Cpcrid%7C64530460840%7C

  1. Calculate $ savings and % savings

$0.50 per stake saved 66% 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. For example: [1]
  1. web page: Department of Energy (DOE) Landscaping and Energy Efficiency, DOE/GO-10095 (1995) Available: http://www.eren.doe.gov/erec/factsheets/landscape.html

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:Outdoors]] [[Category:Shelter]] [[Category:Housing]].
