BMW Quick Disconnect Tool

This tool is for power steering & transmission lines on 1999 through 2006 BMW 3 series and X5 (E46). Compare it to CTA tools 3466. It works by compressing the quick release ring, allowing you to disconnect the hoses easily. 

I added a 13 mm hex socket onto it for leverage/reach. It is probably overengineered, but it's better than it breaking in use. 

I printed with 5 perimeters in PETG with excellent results. No brim was needed, but I did use some supports.
