This uses a 80mm Fan and 130mm filter. The fan is bolted straight into the model with M4 bolts. Both half of the print are glued together. The part that holds the filter will not come out nice without support but will be functional.
Hi @Lukasss I used some generic one of amazon. The one used in the build is this one: https://www.amazon.de/dp/B08JPS6DDP
The connector to the power brick was included with it (https://www.amazon.de/dp/B0C6M3FL31)
Hope that helps.
Definitely worth including these two items into the description (well now it's in the comments, so it helps). I was looking for something like this few weeks ago and went with 3rdparty (entire) set (120mm fan +controller/power unit). Thank you for providing these (and the model as well).
