This is a (sort of) universal mount for the 5 colour Diamond Hot End in OpenScad. It consists of just the parts needed to take the 5 colour hot end and 50mm fan. It isn't a customiser as such but you should add whatever boss or bracket is needed to suit your particular machine. I've included the OpenScad file which I have annotated so you should be able to work out how it works and where you need to add your own mounting arrangement. I'm no expert in OpenScad so the coding may not look pretty but it gets the job done. Feel free to modify it any way you like (just give me credit for the original).
