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!

Tritium Buying Guide

How to get your hands on some tritium? This guide will provide resources and what to be on the lookout for when purchasing tritium. With the shipping disruptions of 2020, prices are all out of wack and should normalize. Note: This guide will not cover the legal aspect as each country has its own laws and regulations. To learn more about the luminosity and spectral intensity of tritium vials, read my post here:  True Brightness of Tritium Vials   Spoiler: Tritium Safety Isotopes should be treated with respect, not only for the safety of yourself but also for the safety of others. The average amount of tritium inside a tritium vial has been observed as such: 3mm x 22.5mm tritium vial is roughly 0.1 curies (3.7 GBq) 5mm x 150mm tritium vial is approximately 1.8 curies (66.6 GBq) Is That Dangerous? It would be inappropriate to say anything other than 'Yes'; however, the risk is extremely negligible. The EPA lightly touches on how tritium can enter and be processed through your bod

True Brightness of Tritium Vials

How Bright Are Tritium Vials? Describing the brightness of tritium can be difficult. People observe the luminescence differently and have differing opinions comparatively. So how can I  genuinely   share the luminosity of tritium vials and rank them?  Below I will showcase my findings using different techniques to put things into perspective. First things first, let's recognize the charting available today; maybe you have seen these or some variation of them:   These images are well over 10 years old and have several variants, some poorly photoshopped floating around. Let's make it our objective to reinvent this chart. Essential to take note, the charts above mostly agree on one thing, the ranking of 'output/yield' compared to each other by color. Spoil Warning , my results don't align with the common consensus listed above.  Looking to purchase tritium? I authored a " Tritium Buyers Guide " to educate people new to purchasing tritium and w

DIY Spectrometer

Tritium Vial DIY Spectrogram To make the best decisions regarding solar cells, understanding the emission of Tritium Vials is critical. A lab-grade spectrometer can cost $5k-$10k, a bit out of budget for this project. Instead, building a spectrometer isn't too terribly difficult. Consumer-grade tools are available that enable the home enthusiast to construct an estimated optical spectrometer that, for general purposes, can be used. The range of this DIY spectrometer is easily between 40nm to 700nm.  To learn more about the luminosity and spectral intensity of tritium vials, read my post here:  True Brightness of Tritium Vials   Spoiler: How to Build this Spectrometer? Credit, where credit is due, this 2016 project by Tony Butterfield,  is the root for this idea; the physical form was replicated to the best of my ability with some improvements.  The code was initially analyzed  and determined to be a guideline rather than a commitment .  The CMOS sensor and features in
