Customizable C-Clip - Updated

thingiverse

I try to design from a purist standpoint, with as little glue and non-printed parts as possible. So I try to print snap-fit parts, which works fine if you can print your flexible parts horizontally. But when it comes to round pegs, it is difficult to print the notched snap-fit pegs you find in commercial projects. When printed, the flexible tabs tend to snap along the layer lines instead of flexing properly. So, my designs, such as the modified prankapult, have been incorporating c-clips. They allow the round (or even square) pegs to have more width since they don't have to be flexible themselves, and still hold everything together. I design mostly in Sketchup, and it has serious issues with precision and has no boolean support. This makes it difficult to properly shape the cutout for the c-clips and I finally got tired of fiddling with it. So, I wrote an openScad (and openJScad if anyone is interested) version so I could make a clip of any size I needed without spending so much time tweaking vertices in sketchup. If you use a decent cad program, it's probably not a big deal to make it from scratch. The peg isn't a big deal even in sketchup, but I've included a file for it as well (since customizer only allows one scad file per "thing", the peg is here). The peg it generates isn't meant to be used a model itself, it is meant to be imported into sketchup and merged with whatever geometry you already have. When printing the clip, I use 100% fill and concentric patterns for infill and top and bottom. This should allow the most stability during flexing, as very little force will be in a direction trying to separate strands.
