Universal cross key

prusaprinters

<p>I needed a universal cross key like this one for my job. Found one on the thingiverse, but I found it not strong enough. So I decided to design my own.</p><p>Used dimensions found on the internet and designed it with Autodesk Inventor professional 2015.</p><p>Just load the .stl, scale 10x, rotate 90* on x- or y-axis and start printing.</p><p>Don't forget to enable support material. You might be able to print without, but for the best results you need some support.</p><p>For more tips on this print, see instructions.</p><p>If you want to edit this thing, feel free to do so. I've added the .ipt file for easy editing.</p><p>(10x scale has something to do with my inventor settings. When I export the .ipt to .stl, it automaticaly scales it down for some reason. Just scale it up 10x and you are good to go)</p><p>Pls post a comment with your pros, cons and tips!</p><h3>Instructions</h3><p>Enable supportmaterial - Some ends of this key are smaller then de key itself and therefore they are not touching the printbed. Use supportmaterial to solve this problem.</p><p>Minimal 4 Perimiters - For better printresults on banked edges and a stronger key, use minimal 4 perimiters.</p><p>Minimal 30% Infill - More infill means a stronger key!</p>
