Rostock VGA PEEK fan holder for J-Head

Wanted to have a nice PEEK fan like the parent thing but also wanted to re-use some cheap VGA fans we bought in quantity. Therefore a new thing was born! Complete redesign in openSCAD but it's fairly hacky so I'm not making it a customizer thing. Designed to be tapped for the fan mounting holes. I don't think ABS (and other softer materials) will take machine screw threads as well as PLA but I haven't tried. Considered a work in progress because it hasn't been mounted/tested on anything yet.
