Summary

FlashForge Dreamer Side Panel Fan Mount

The side panel fan mounts are designed to replace the Dreamer's snap in side panels allowing you to mount two 80x80x15mm fans on the left and right side of the Dreamer as I have done with my own Dreamer. It's possible these MIGHT fit the Dremel as well.

Two styles of fan mounts are included.

The flat side panel fan mount is designed for the left side. Because it's flat on the outside, it allows the printer to stand on it's left side wall when doing maintenance, which is something I do often.

The outset side panel fan mount is typically mounted on the right side, giving better clearance for the internal parts. I don't put this on the left side because I usually lay my printer on it's left side when doing maintenance. It's not good to stand the printer on it's left side to do maintenance if using the outset side panel, because the outset panel will break.

Note: the photos are outdated, showing my older design.

The wiring diagram shows how I wired up my 4 extra fans using a step down converter, a thermostat, and a switch to override the thermostat (see the FlashForge Dreamer Thermostat Mount for details).

FlashForge Dreamer Thermostat Mount
Feb 5, 2015 - Modified Feb 5, 2015

Hi ncapaldi1985,

I will devote an entire thing page to my custom cooling additions showing the details of my setup, which will include photos, instructions, models for the thermostat, etc.

I used extra power terminals already available on the FlashForge Dreamer's power supply (the large metal box on the bottom center of the machine) to supply 24 volts to a step down converter, which then converted the power to 12 volts. This 12 volt power was then connected to a 12 volt thermostat (I couldn't find a 24 volt one that I like), and a 12 volt lighted LED switch. The switch is used to connect power to the fans directly, bypassing the thermostat, so that I could turn the fans on manually. The thermostat (I'll give details about this in the thing file for it that I'll make soon) is set to turn on the fans when the temperature reaches a certain level. I set mine to 45 C to ensure that the inside temperature of my printer never reaches the glass transition temperature of PLA during use.

The thermostat used is found here: http://www.amazon.com/gp/product/B00GWFK7FA

The switch I used is found here: http://www.amazon.com/gp/product/B006OR91UI

The step down converter is found here: http://www.amazon.com/gp/product/B00H3YN9H2

The fans should be 80x80x15mm fans. I used 12 volt fans because my switch's LED was rated for 12 volts, but even though the thermostat is powered by 12 volts, the thermostat's relay should work for 24 volt fans. But since I couldn't find a 24 volt thermostat that I liked, and I therefor had to use the step down converter, I opted to have all of these extra items run from 12 volts.

Putting everything together was pretty easy. It's just all wired together directly, no other electronic parts were needed.

When I post my thing file for it, you'll see it's a pretty simple setup. I also have extra LED strip lights installed in my Dreamer which are also powered by the Dreamer's power supply, which have their own devoted switch. But that's a different project.

quick question where did you wire the fans to?
