Centauri Carbon Recirculating & Noise Reduction Air Handling Assembly

This is the first release of a model that I intend to refine further. Help test this out, provide your feedback. This assembly reduces auxiliary fan noise and improves chamber heat retention. While also preventing the buildup of hot spots within the chamber by recirculating the air. At this time, there are no instructions aside from what is covered in the video below. An installation and noise comparison video will be coming out in the next few days.

You will need M2 self-tapping screws to assemble it properly. I'm using 15 of the 6 mm screws from that assortment. The 6010 fan is optional. 

Non-OE fans seen in the video:

• Winsinn 6010 dual ball bearing 
• Wathai 7530 sleeve bearing fan

The Wathai is a sleeve bearing and not recommended for anything you want to last a long time. The recommended fan model has a dual ball bearing, similar to this WDERAIR 7530 fan. Unfortunately, there are not many good dual ball bearing options readily available for 24v 7530 form factor fans.   

At a minimum, you can use the stock fans. This will also allow for the reuse of the passive daughter board from the OE enclosure. 

The filament used is Elegoo Rapid PETG.
