This bundle is 30% OFF & has 3 models: v2, v3 & v4 of Case exhaust for Lenovo D30, fitted to attach the original Lenovo exhaust fi120mm case fan (AVC DS12025B12U) out of the case, as this is needed for modification of the flow & cooling, while preserving fans on Lenovo motherboard. My reason for that is the change of cooling in Lenovo D30 from original Lenovo cooling CPU coolers to Noctua NH-U12S on CPU0 & NH-D15 on CPU1, which dropped the CPU temperatures under full load from ~80°C to less than 60°C. So slow Lenovo/AVC fan was spinning to slow for moving of air outside the case.

In models there has been added:

• v2 is the 1st good prototype made by me & fitted on to the case
• v3 has support for washers in M5 tightening support & side support for less pressure on a wall
• v4 has support for anti-vibration mounts (tested with NA-SAV3) or rubber washers in M5 tightening support & side support for less pressure on a wall to be used with 1mm anti-vibration leg softeners

The model fits perfectly to the case & to the fi120mm fan, has enough room for wiring to the motherboard & will improve your setup for Lenovo D30 machine.

For 3Dprint, don't forget to use temperature resistant materials with can handle at least ~80°C or more & make sure you use supports for 3D print. I have used PETG, but more temperature resistant materials are advised.

For fitting, I have used 6pcs Noctua NA-SAV3 anti-vibration mounts, instead of originals (much harder rubber ones). Also, wiring for case fan is ducted outside the case & goes in through the 1st card slot in the D30 case (just make sure you isolate at least ~50mm of the fan wiring in order not to damage it on sharp edges).

Also, the fan protection needs to be replaced from intake to exhaust area - see the prototype assembly in pictures. Brackets are a little thicker then on prototype in v3 & v4 model, but if needed, put some washers or distancers for better holding.
