NexGen3D: CleanAir Filter System MK2 with Magnetic Dock

This is my new CleanAir system, I've made several improvements over the previous version:

1. Thicker lid and rail system
2. Magnetic pogo pin system
3. Multi stage filer system
4. Cleaner style
5. Various model fixes

With this new design you can rapidly change the filters, myself I have made a few of these and I just quickly swap them out as needed, I also use several thin layers of carbon pallets, and several layers of foam hepa filter, the multi stage system allows you can use a variety of different filter medium combinations.

The magnetic dock can be bolted to 2020 rail, screwed down to a panel, or in the case of my K1C, I just glued it in place with superglue.

Quite simple to assemble, just pay attention to the polarity of the wires and also the magnets, if the fans don't slid in firm, then you can use a couple of spots of superglue to hold them in place.

I used GDStime dual ball bearing fans due to there long life and high performance, I don't recommend using cheap sleaved bearing fans as they will not work well and can die prematurely.

Requires:

• 1 x M3x10 BHS
• 1 x M3 Heat Insert
• 2 x GDStime 5015 Dual Ball Bearing Blower Fans
• 1 x Set of Pogo Pins (Male Female Wires)
• Superglue
• What ever filter medium you like

I used a small amount of superglue to stick the 10mm M3 bolt into the thumb screw, small amount of glue on each fan, and some to stick the pogo pins in place.

You can print the lid in multi colour on any machine, the accent is only a few layers deep so only 2 or three manual filament changes required, you can also just print all in one colour, just drag both Lid, and Lid Accent models into your slicer together.

I've been using these for around 6 months now in all of my machines, and I'm quite happy with them, so I thought its time to share, for large enclosed printers, I recommend 2 of these, smaller machines like the K1C, one is enough, I use strips of Hepa filter, activated carbon pads and pallets, I find the pallets are good enough, just change them often and don't use to many, just a small amount in each chamber.

I also recommend vertical mounting only, up or down is fine, the magnets are strong enough to hold in place, but I don't recommend mount horizontal as the pallets will all collect to one side and the air will bypass them.

I've added the Klipper config file from my previous CleanAir system, instructions are in the config file.
