TL;DR - I modeled a corner bracket using Blender in a somewhat parametric manner. If you want to look at the file and see what I did you can find it here. You can also skip down to the modeling section to see exactly what I did. Recently I replaced my Duplicator’s Melzi controller with something a little more sane. I’ll write a blog post in the future about the dependancy hell required to actually get a Melzi to work but for now, I need a bigger space to put my Smoothieboard in.
