Anycubic Mega i3 hotend cover

Here we've got a silent hotend cover inspired in https://www.thingiverse.com/thing:2457516. I'm using two Noctua 40mm x 10mm fans to cool the hotend and the printed part. Noctua fans provide a low airflow so I'm redirecting and funneling the output to the nozzle's end and seems to be enough. You don't need to change the hotend angle and keep original bolts (you'll need 4 M3 nuts) to attach it to the carriage. You´ll also need 20mm M3 bolts and nuts to attach both fans. If you don't use the fan covers, 16mm bolts will be enough for the hotend fan. I've added some part's fan output options. The one I've chosed for my printer is the one with 8mm x 4mm output to concentrate the airflow on the nozzle's end. The part's fan output is attached directly to the front fan so designing your own airflow output should be easy if none of my options matches your needs.
