RatRig Alu Printhead(VZBOT) fan duct with beacon

Direct airflow for the RatRig Vzbot alu printhead as until now there was no other option than the Tentacool. I personally prefer this more.


The CPAP back is from :

The spacers you can use the official ones and scale them to 7mm or this printed ones. Personally i use aluminium standoffs :
2/ 5/ 10pcs M2 M2.5 M3 M4 M5 M6 M8 M10 M12 304 Stainless Steel Hex Standoff Spacer Long Rod Coupling Hex Nut Bolt - AliExpress 13

What you also need :
4x M3 3,5/4 Lenght, 4.5 OD heat insert. Only 2 if you have no beacon/cartographer.
