Abstract

This type of clip is found on a variety of items, most commonly backpacks, and work well. However, I have found that if you break one, it is difficult to find a replacement, and are overpriced (typically $2-6 for 1 set!). Since it is made of plastic and only plastic, I wanted to make a parametric OpenSCAD design. There are many designs for there out already, however few provided source code and even fewer were scalable.

Bill of Materials

Filament of your preferred color
Design files as found here

Tools needed for fabrication of the OSAT

MOST Delta RepRap or similar RepRap 3-D printer

Technical Specifications and Assembly Instructions

Print out the part. Be prepared to remove the support structures.
Print time: ~40 mins.

Cost savings

3D printed part: <50 cents (depending on size)
Commercial part: $2-$6
Minimum cost savings of 75%

 == 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
+# Filament of your preferred color

-== 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.
+# Print out the part. Be prepared to remove the support structures.
-# Include print time estimate
+# Print time: ~40 mins.
-# 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.
+# 3D printed part: <50 cents (depending on size)
-# Estimate your costs
+# Commercial part: $2-$6
-# Find a commercial equivalent
+# Minimum cost savings of 75%
-# 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 <nowiki> <ref> </ref> and <references/>  </nowiki>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: <ref> web page: Department of Energy (DOE) Landscaping and Energy Efficiency, DOE/GO-10095 (1995) Available: http://www.eren.doe.gov/erec/factsheets/landscape.html</ref>

-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]].
