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.

Tools needed for fabrication of the OSAT

  1. MOST Delta RepRap or similar RepRap 3-D printer
  2. Exacto knife or similar product for removing support structures


Technical Specifications and Assembly Instructions

  1. Print out the part. Be sure to generate supports for the print. Be prepared to spend time removing the the support structures.
  2. Print time: ~40 mins.


Cost savings

  1. 3D printed part: ~50 cents (depending on size)
  2. Commercial part: $2-$6
  3. Minimum cost savings of 75%
