My final objective for this series of experiments is to accomplish silent part cooling, as that is the only weak point of the fanless machine. Need to use some kind of chimney, laminar flow, thermal engine, thermoacoustic engine, phase change witchcraft, re-radiator, contact coolers, or other such nonsense to pull it off, but we'll get there! If anyone has ideas for how to pull it off with a practical solution I'll build it, and make a video about it and give you mad kudos.

Ender 3 Pro - Fanless Edition 

Quietest printer to date.

No Fans, Silent Stepper Mainboard (SKR Mini 2.0), CPU heatsink, and LED ring light

Ender 3 Pro Silent Fans and Silent Stepper Mainboard

Prior attempts at Quietness using "silent" fans, but they are nowhere near as silent as the fanless builds

Ender 3 V2 Silent Fans + Volcano

Not quite as quiet, but prints fast and is pretty quiet, so that's cool too

Making Printrbot Simple Metal Quiet

Different model of printer. This was a practice run to see if I could bring an old derelict printer back to life as a silent phantom. It worked, but has pretty low views cause nobody cares about Printrbots anymore :( still an interesting build and a nice printer in my opinion. Learned a lot on this project.
