Customizable C-Clip - Updated

thingiverse

I strive to design from a minimalist standpoint, minimizing glue and non-printed components whenever possible. To achieve this, I opt for snap-fit parts, which work flawlessly when printing flexible components horizontally. However, when dealing with round pegs, printing notched snap-fit pegs found in commercial projects proves challenging due to the tendency of flexible tabs to snap along layer lines instead of flexing properly. To overcome this limitation, my designs, such as the modified prankapult, incorporate C-clips. These clips enable round (or even square) pegs to have increased width since they don't require flexibility themselves and still maintain structural integrity. I primarily design in Sketchup, but this software has significant issues with precision and lacks boolean support, making it difficult to accurately shape cutouts for C-clips. Frustrated by the time-consuming process of tweaking vertices in Sketchup, I developed an openScad (and openJScad for interested users) version to create clips of any size without extensive manipulation. For those using a proficient CAD program, creating this design from scratch is likely straightforward. Even within Sketchup, the peg component is manageable; however, I've included a file for it as well due to customizer restrictions (allowing only one SCAD file per "thing"). The generated peg is intended for import into Sketchup and merging with existing geometry. When printing clips, I employ 100% fill and concentric patterns for infill and top and bottom layers. This approach ensures maximum stability during flexing by minimizing forces attempting to separate strands. **Print Settings** * Printer: Monoprice Maker Select V2 * Rafts: No * Supports: No * Resolution: .1 * Infill: 100% concentric **In Use** Tiny C-clips are used to secure a circuit board mount within an enclosure. **Updates** February 6, 2017 - Added top and bottom chamfers to round edges and facilitate removal from the bed.
