Universal cross key

thingiverse

I needed a universal cross key like this one for my job. I was thrilled when I found one on Thingiverse, but unfortunately, it wasn't strong enough for me. So, I decided to design my own. I utilized the dimensions I found online and designed it with Autodesk Inventor Professional 2015. Just load the .stl file, scale it up ten times, rotate it ninety degrees on the x- or y-axis, and start printing. Make sure to enable support material, as you might be able to print without it, but for optimal results, you'll need some extra support. For more detailed instructions, check out the provided notes. If you want to edit this thing, feel free to do so - I've included the .ipt file for your convenience. One note about my settings: when exporting the .ipt to .stl, it automatically scales it down, so just scale it up ten times and you're good to go. Please share a comment with your thoughts on this print, including any pros, cons, or tips! Sorry for my English; it's not my primary language. Instructions Enable support material: This key has some delicate ends that might not touch the print bed. Use support material to resolve this issue. I used Slic3r and let it detect where the support material was needed. Use a minimum of 4 perimeters: For better printing results, especially on curved edges, use at least four perimeters. This will give you a stronger key. Opt for a minimum 30% infill: To create a sturdy key, print with at least 30% infill. While more might work well, the ends are already prone to breaking at this percentage.
