CAD Hole & Cutting Tool For Noctua Fan Screws

I am making something where I am re-using some screws from Noctua fan kits, as it turns out I have saved rather a lot of them and it's a shame to not use them, and now you can too.

This page contains a STEP file and a Shapr3D CAD project containing a hole that works with such screws as well as a cutting tool. They are the correct size and can be used without resizing.
