EVENmore - Bed Fans with Style

When building my Voron I was looking for a nice bed fan solution 🤔 that would fit my Nevermore and help to bring the chamber temperature Even More up🔥 to where it belongs. Since I couldn't find anything that I really liked, I decided to go to the drawing board. And here they are: bed fans that match the Nevermore Micro perfectly 🥰 (not only the Micro V6 and of course they work standalone as well 😉)…

Support me : Please leave a ❤ Like if you actually like and use this model. It does help a lot to get some of the filament that is needed for all the test prints while creating models to share with you! And check out my other models if you're building a Voron!

Model Details

Essentially, this is a single fan version of the Nevermore Micro V6 with a modified cartridge that only acts as an air duct. Everything is designed to keep the width of the case as small as possible. It fits perfectly under the 300 bed version (see images below), but also works for the 250/350 beds.

I chose to leave the magnetic cartridge at the front (although that requires  an investment in some magnets 💰): Not only does it allow for easy access to the M3 screws for attaching the case to the frame, but the two-piece design also allows for attaching custom designs tailored specifically to your needs, e.g. air outlets at the front or side.

…and Some Smaller Details

• It features a second attachment point in the back (M3 heat set insert) and there is a little mount bracket for 2020 extrusions that attaches right there to keep the babes wiggle-free under the bed. And if you like, you can easily design and attach any other bracket or part that you need for your specific setup.

• If you don't want to to a JST plug there is also a little generic cable plug: Guide the cable through the outlet and the plug will keep it in place - solderless!

• In the original Nevemore design, the lid had a small notch that snapped into the case. However, this mechanism was far too cramped in this smaller package in my test prints, especially when printed in PCCF. Therefore, the lid only has a minimal notch. If for some reason you want this full notch, it is also in the files section.

Build Guide

Take some time⏱ get a drink 🥤and build it with love 🥰. There are some steps that require some patience, it's not designed for mass production 😉. No worries you will manage it!

BOM

• Fan

  • 2 pcs 5015 Blower Fan 24V

• Heat Set Insets

  • 4 pcs M3x5x6mm ( "standard" Voron)

• BHC

  • 2 pcs M3 (min length 4mm, max lenght 10mm)

• SHC

  • 4 pcs M3x8mm

  • 1 pcs M3x 10mm

  • 1 pcs M3x 20mm

• Magnets

  • 16 pcs 6x3mm (high temp, e.g. NdSH-Ni))

• T-Nut

  • 4 pcs M3

Printing

Filament Type: These babes go under your bed where it is warm and cozy. So use some heat resistant filament. The absolute lower end of the line is ABS / ASA and I highly recommend to use PCCF or similar

Settings: User your standard Voron settings.

Orientation and Support: The parts are already oriented for printing. But you will need to set support for the following parts

• Case: It needs quite a bit of support on the top area, specifically where the cable channels are, and also along the air path. Use paint-on supports (tested automatic support generation in Prusa Slicer and it was also fine… so if you are lazy, just give it a shot), set supports to organic and check the slicing results.

• Lid: Just for the recess for the screw

• Mount Bracket: Support the part that goes into the 2020 extrusions

Fan Preparation

You need to carefully cut off the top mounting notch of the two fans.

• With a rotary tool, the work only takes 5 minutes.

• Make sure it perfectly fits into the EVENmore case

• … and check that the fan is aligned centered to the air inlet.

Magnet Installation

Use some Super Glue to install the magnets… and of course check for the correct orientation/polarity.

Wiring and JST Connectors

In the following I will show you the nice way to manage your cables, which requires you to cut the cables to the exact and correct length.  There is also a second option which I added later to make it a bit easier: Route the cable along the green line from the center of the fan into the EVENmore case. At this position there is a larger cutout in the housing that allows for easy access to the cable duct. And there is "plenty" 🤣 of space to tuck away some cable after the fan is installed. So you do not need to cut the cable to exact length.  Of course, for everything else,follow the steps described below.

Cut the fan's cable to the correct length. 

If you don't want to use a JST connector: Do not cut the cable! You can just skip these steps completely.

• Insert the fan into the housing and guide the wires though the cutout in the printed part. It will help to pre-bent the wires as shown in the first picture.

• Make sure the fan still gets flush into the EVENmore.

• When everything is in place perfectly, cut the wires flush with the housing (do not pull on the cable but let it just hang loosely out of the case!). This gives you the perfect length to wire it up and have some slack to get the fan in and out.

• In the pictures the steps are shown for the right fan case. Of course, do the same for the left one.

Solder the JST Connector (or use the Cable Plug)

If you don't want to use a JST connector: You can simply guide the cable out of the housing and use the cable plug to fix it in place. Do not cut the cable in this case but follow the steps below for guiding the cable inside the housing.

• Raise the fan to be able to pull some cable out for soldering

• Solder on the JST connectors

• Carefully press in the JSTs, e.g. use a vice or other tool that allows parallel pressing

Final Fan Assembly

• Start from the pressed in JST Connector an work your way along the cable channel. Use tweezers to push the cable where it needs to stay.

• You can also use tweezers to keep the cable in place while you slide the fan into the housing

• Check that everything fits perfectly

• Insert the fan clamp….

• …. and close the door 🤠 

Mount the babes

• Install the mount brackets if you want

• Mount the EVENmore to your frame

• … and attach the magnetic front parts.

Finish-up the installation

• Checkout the JST-Hub and Cable Clips to for your cable management.

• Install your print bed,

• … grab a drink 🍹 and enjoy your work 😎 !
