CREALITY ENDER 3 Nozzel vent

**20/5/2019 - V2 available here. https://www.thingiverse.com/thing:3639454**

I saw and liked the Ender 3 vent ring created by Filboyt so I printed it. It fitted a dream and the 'bowl of water test' showed it performed well. However when printing, I like to watch my printer lay down the 1st layer and sadly this prevented me seeing anything.

So I took Filboys vent and a pair of calipers and measured the mounting assembly and recreated it in Sketchup as it fits perfectly.

I then created an new air duct system which allows you to see the nozzle while printing. I checked it with the 'bowl of water test' and it works well.

I'd like to say that Filboys creation is AMAZING (and possibly has slightly better airflow) but I'm very new to 3D printing and still feel the need to keep an eye on things. I'm sure in the future when I'm more experienced and my 1st layers are consistently reliable, the need to watch closely may not be needed,
