Less loud Anycubic Mega Zero v1/v2 Hot End Shroud
Description
The stock hot end fan on the Mega Zero is notoriously loud. Except it isn't. When I had it running outside of the cover recently, it hardly made a sound. As [TTalkington](https://www.thingiverse.com/TTalkington) so succinctly remarks in his comment on [Mighty Nozzle](https://www.thingiverse.com/mightynozzle)'s [Customizable Fan Grill Cover](https://www.thingiverse.com/thing:2802474), the wrong fan guard can make a hot end fan sound like a professional leaf blower. The stock Mega Zero fan guard is a perfect example of this. I have been meaning to print [Calvin MegaZero](https://www.thingiverse.com/calvin_megazero)'s very nice [Frankensteiner hood combo](https://www.thingiverse.com/thing:4709536) to replace the hood, but in PETG with my preferred settings this is a long print, so I need to plan it for when I have the house to myself for a full day because my partner is not a fan of leaf blowers. So when I saw [Peter Denyer](https://www.thingiverse.com/pjdenyer) had uploaded the [Anycubic Mega Zero v1.0 Hot End Shroud](https://www.thingiverse.com/thing:4863391), I knew this was my chance to silence the fan. Hence this remix, which is a combination of the [Anycubic Mega Zero v1.0 Hot End Shroud](https://www.thingiverse.com/thing:4863391) and the Aperture version of the [Customizable Fan Grill Cover](https://www.thingiverse.com/thing:2802474). Of course you can still hear the fan, but the high pitched whining is gone. There are **two main versions** of this design, because some 4010 fans have **round holes** around the screws and others have **hexagonal holes**. Check your fan before you print. If you are not sure, the hexagonal design should also fit a fan with round holes but the design with round holes might hold the screws or brass insert nuts better. I printed the original version, then found out my fan had hexagonal holes so I cut away some material around the insert nuts. As you can see this was not good for the hold of the insert nuts. Because I have mixed experiences with insert nuts, I also created a self tapping version of both designs.
