SpriteBurner Ender 3S1 Cooling duct based on StealthBurner (tested CHCB-OT hotend)

There is a newer version v2-

I really love the StealthBurner look and wanted to make a cooling duct that has that cool turbine look for my ender 3 s1.

And here we have StealthBurner-Sprite or what i like to call SpriteBurner. 

This is just a fun project for me. I absolutely loved working on this

Although i have done some CFD simulation to tune the ducts I do not claim this to be any better than other fan ducts out there. But this probably has to be maybe one of the coolest looking one.

Duct is designed with the chcb-ot hotend in mind.

My first attempt  to make something like this also first time using heated inserts. So forgive me for the complicated assembly.

Uses

 2 M3-8mm

 1 M2-8mm bolts to connect the face with the duct.

1 M2-6/8mm to connect the bottom led cover if you went with that.

Cut the 5015 fan shroud top and its screw mounting legs like how its done on StealthBurner.

Uses single 5015 fan (DO NOT USE DOUBLE BALL BEARING FANS, check notes).

LED optional you need to figure out the mounting method The uploaded file can hold single 8mm straw hat LED at the center of both ducts.

There is window for inserting led for logo if you want. Passing the wire through is tricky but possible. I suggest pass some thread or spare bendy wire through then use it to pull your LED wires. I went with same style led. without any mount just  pressed it in there.

I just used a piece of paper to cover the window and jammed in whatever spare 8mm led bulb i had

Steps files included

Here is also the onshape document that i worked on.

you can also find by searching StealthBurnerSprite on onshape.

 WARNING NOTES*

I found the hard way that you cannot use ball bearing fans with this design. Because of the position and distance The stepper magnets pull the ball bearing towards it kinda slowing the fan down at lower speeds. Its a bummer. But you can use regular sleeve bearing fans. 

Right now i am using a creality 5015 brushless blower fan and is working fine.

Next..

I have already started working on a second version with a bit of gap between to avoid the magnetic effects of the fan and stepper. 

And maybe move to a 5020 fan to utilize that gap as a secondary intake. 

Perhaps make it shorter?..

Would love your feedback.
