CWWK Mini N Series Case Extender

The CWWK Mini PC N Series case has a 80mm case fan mount, but you'll need a 10mm one and then it intakes and vents on the bottom. This extends the case down 25mm to fit a standard case fan and adds side venting. It reuses the default case bottom. You can also easily route the cable for an external fan through one of the vent holes.

Unless your printer is amazing at bridging you will probably want to enable supports, I suggest organic. I used 0.2mm layers (Structural), 15% infill.

You'll need four M3-0.5x35mm screws, a fan (I recommend the Noctua NF-A8 PWN), fan mounts (the Noctua comes nice silicon ones instead of screws). Hook up the included fan splitter if you want to run a top fan too (I put a Corsair ML120 on top of mine).

Note that the CWWK fan header is a Micro JST MX 1.25 4 pin connector (12V, PWM), my unit came with an adapter cable but if you don't have one, they are not to hard to make, they sell pigtails on Amazon.

For my use case (running VyOS 1.4 in a closet), the NVMe temps dropped from +47.9°C to +31.9°C, a bigger improvement than I had hoped for. And that's with the fan running so slow I can't hear it right in front of me.
