## My 3D printer is 100x quieter than yours! ** It's a bold statement but this is how decibels work! In my project I took Ender3 and Ender 3 v2 machines and modified it to make them almost completely silent! To achieve this I had to tackle the part cooling fan. I came up with a design that uses 24V radial fans (5020 and 4020) and runs them at 12V instead for the ultimate performance. This design is optimised for: - Ender3 with a stock extruder - BIQU H2 series extruder (including watercooled H2O) part list: - AMount - H2 series mount - Modular Blower Mount - Ender 3 series mount - A5020 - adapter for 5020 series fan - A4020 - adapter for 4020 series fan You can read more about silencing your printer here: https://notenoughtech.com/3dprint/silent-3d-printing/ To use the STL, please print with support, and consider using the parts from Amazon list: - [5020 24V fan](https://www.amazon.co.uk/gp/product/B08W1VBGFK?ie=UTF8&psc=1&linkCode=sl1&tag=notenoughtech-21&linkId=97d7e9535712cbe77666561db672f14d&language=en_GB&ref_=as_li_ss_tl) - [4020 24V fan](https://www.amazon.co.uk/gp/product/B08W1VBGFK?ie=UTF8&psc=1&linkCode=sl1&tag=notenoughtech-21&linkId=97d7e9535712cbe77666561db672f14d&language=en_GB&ref_=as_li_ss_tl) - [24V-.12V stepdown module](https://www.amazon.co.uk/gp/product/B08W1VBGFK?ie=UTF8&psc=1&linkCode=sl1&tag=notenoughtech-21&linkId=97d7e9535712cbe77666561db672f14d&language=en_GB&ref_=as_li_ss_tl) - [threaded inserts](https://www.amazon.co.uk/gp/product/B08W1VBGFK?ie=UTF8&psc=1&linkCode=sl1&tag=notenoughtech-21&linkId=97d7e9535712cbe77666561db672f14d&language=en_GB&ref_=as_li_ss_tl) - [JST connector kit](https://www.amazon.co.uk/gp/product/B08W1VBGFK?ie=UTF8&psc=1&linkCode=sl1&tag=notenoughtech-21&linkId=97d7e9535712cbe77666561db672f14d&language=en_GB&ref_=as_li_ss_tl)
