MkV Dual Cooling 40mm Fan Attachment for Kossel Mini

This is a remix of 3ddelta's Mk IV hotend cooling shroud, shortened by 3mm so than the Mk V hotend nozzel protrudes below the level of the shroud. I've also thinned the hotend "U" keeper by 0.25mm as I found the parent thing too tight when I printed it on my homemade Kossel Mini. YMMV

This is my first attempt at using DesignSpark Mechanical, so no guarantees on my modification, but it printed as well as the parent.

**Update**: I've trimmed another couple of millimeters off the bottom
