-The re-design needs some further tweaking before I can publish it. I will continue work on the re-design after my exams are finished on 12-4-19. Thank you to everyone for your feedback and please be patient a little while longer.
I am working on improvements in the design
-optimize the model for printing without "fill thin gaps", this saves about 30% of print time.
-bltouch mount redesign that allows the sensor the be mounted in two ways to accomodate different sized knock-off sensors.
-stronger vanilla and vanilla + endoscope fan mounts
-a clip on the right side to prevent vibrations during fast printing
-stronger endoscope mount to prevent the endoscope cable from twisting the mount sideways over time.
-integrated cable clamp in the fan duct
-improvements in the fan duct to prevent blowing against the silicone sock.
-move focus point of the endoscope mount lower to prevent the heating block from filling up half of the screen.
I am also planning on a 5015 version, which will probably be up around the 24th.
A fan mount that is very quick and easy to print and directs the air more effectively towards the nozzle.
- bltouch mount option very close to the nozzle
- EZABL mount option
- endoscope camera option
- no support needed
- 3 hours print time
- better part cooling
- only stock parts
BLTouch offset: 27mm to the left & 1.7mm behind the nozzle.
EZABL offset: 42mm to the left & 5mm in front of the nozzle.
Also compatible with the ender5 if you cut away a tiny portion beneath the leftmost mounting hole.

why design another ender 3 fan mount?
I purchased a cheap endoscope camera (7.4mm diameter) to watch my prints in detail from the comfort of my chair. The only problem was that the stock ender 3 fan mount completely blocks the view. In my search for an alternative fan mount I was unable to find something that:
- required no support
- was compatible with both the stock fans
- had a bltouch mounting point
- had the bltouch close to the nozzle
- had enough clearance for the endoscope camera.
With these points in mind I designed my own fan ducts and mounts.
designed for 0.4 mm nozzle, other nozzles will probably not work.
The complete mount can be printed in two pieces without any support.
Use a brim for the main body.
Do not use a brim for the duct because it has a built in brim.
Some people and myself have experienced the right wall of the main fan body failing, I recommend enabling z hop to prevent this issue.
I printed in PLA and it's fine temperature-wise.
Total print time is aprox. 3 hours, 1 for the duct and 2 for the main body.
I included the fusion360 archive so you can easily alter/remove the camera and bltouch mount.
5015 version of the fan duct
integrated cable clamp
only endoscope mount version
some kind of clamping mechanism to better constrain the right side of the mount to the printer frame
changed the fan duct slightly to better direct the flow towards the nozzle, was a mm or 2 too low previously.
