Silent Ender 3D Printer

Silent Ender 3 w/ Noctua Fans

Less a DIY tutorial and more a parts list showcasing the success of this project.


I was over the moon when I purchased my first 3D printer. It wasn't long before I found myself upgrading one piece at a time. In early 2020, my basement, where my 3D printer lived, became my Work From Home (WFH) office. My 3D printer was too noisy to be running in the new office. 

I still had the original V1 motherboard and fans supplied with the original Ender 3 V1. If you own this printer, you will understand that it basically sounds like a jet engine at all times. This wouldn't do if I were to have it running while I was working from home.


I have always been a big fan (pun intended) of Noctua fans. A quick Google search yields many attempts integrating Noctua fins into the Ender 3 with success. 

Short parts list:


  • All parts plug and play well, get some machine screws for attaching the Fans to the front of the duct.  
  • DC to DC Buck Converters is installed inline with each fan after calibrating to the proper voltage.
  • Each buck converter is wrapped in electoral tape so they can be tucked away without shorting out on anything metal.
  • The 60mm fan requires a hole to be drilled in the power supply to run the wires directly and cleanly.


  • Would I do this again? Yes.
  • Do professional 3D printers believe this is a viable and appropriate solution? I received constructive feedback suggesting this would self-destruct. Over 500 hours run on this, running great!

Dyson Cyclone Mod for Roomba S9

Cyclone Filtration in Roomba S9 Base Station Possible? Yes Chance of Failure? Medium STLs and Fusion 360 are linked below. Project Intro: Objective: Design and 3D print a replacement to the classic iRobot Roomba Station Bags. Never before have I designed a cyclone filtration solution, which required a lot of research.  Design: Cyclone Testing: Surprisingly, a nearly random cyclone shape worked very well in small-scale tests. Time to scale up! This time, we are testing varying particle sizes and different aperture sizes. Again, very surprised by how well it worked! I connected these to my Dyson V12 for consistent, reliable suction in particle testing.  After 40+ hours of printing and trial-and-error testing, I was ready to begin the final design as the first proof of concept. Findings: There is a scientific method to approaching this, and a complete understanding of several external factors would need to be known to render the best possible cyclone. Factors such as suction power and par
