Cooling Fan Shroud for Creality Ender-2 by lewtwo
by Thingiverse
Last crawled date: 3 years, 1 month ago
EDIT 26 Apr 2018:
Note this shroud will NOT work with the older model Creality 4 fin heat sink unless the bottom cap screw is replaced a proper set screw. This shroud will work with the newer model Creality 9 fin heat sink that uses a proper set screw.
EDIT 20 Apr 2018: Added PDF of X Carriage Plate
What the world needs is yet another cooling fan shroud for the Creality Ender-2. Not really but it does need one that works. I say that because at least two of the more popular designs have an interference with the lower X-Axis axle bolt. I tried a number of others and did not find anything that I deemed suitable but then I have sort of a warped idea of what is acceptable. So I did a new design in BricsCAD. The goals were:
1) No points of interference
2) No printing supports required
3) Symmetrical (consistency and symmetry are next to godliness)
4) Use standard sized 40 x 10 mm cooling fan
5) Be able to see the print nozzle
6) Withstand at least 230 degrees print temperatures without damage
7) Usable when printed in standard PLA
What I have come up with is made of two parts solvent welded together. The final version is the result of numerous trial and errors. The design that I am posting has run nozzle heat at 240 degrees with no detectable damage. I have used this fan shround on the Ender-2 to print PLA, FlexPLA and ABS. While it is usable when printed in PLA, I recommend using a higher temperature filament like ABS.
I realize a number of people use some form of Cyanoacrylate such as superglue but these do not work as well as solvent based adhesives and they have a short shelf life. I used SCIGrip #16 but others such as WeldOn or Testors part No 3509C should work just as well. I also recommend lightly sanding the bottom surface of the assembled fan shroud with 400 grit wet sand paper. Be careful ... that is a very thin wall.
I have also included a two part cover for the fan just to prove how anal retentive I can be. I printed this cover with Parmount’s FlexPLA with the idea that it might make my Mini-Kaze SY124010L fan a bit quieter. It is not any quieter but I like the aesthetics. With the fan cover all six of the required fasteners are M3 x 16mm.
My major problem in starting this project was in getting some basic dimension of the hot end. Thus the first thing that I had to draw was the Creality Ender-2 Mk8 hot end. For those of you that might be interested I have also included that drawing. For those that might want to “mess with perfection” (did I actually say that ?) I have include the original DXF model files as well.
