3D model description

Briss Moto design

Just to make things clear, my designs are protected by copyrights laws. It is not authorized to distribute or sell any of my designs without prior written authorization from myself. Even if you modified my original design. Thank you

Update 04-05-2021: Adding ender 6 models, upgrading all to V4.3 (slotted mount holes for 2mm height adjustability) and adding "fan duct up V2" which has integrated grill. It's more tricky to print because of the small features so i'll leave both files on here.

Update 6-03-2021:
-Adding compatible files for Micro swiss direct drive carriage. Again available with or without LED's
-Adding BL touch bracket

Update 25-02-2021: V4.2 Now available with integrated LED lights (5mm straw hat LEDs up front and possible to put a 20mm star inside). Both files are available, with or without lights. It's a little more tricky to print the one with lights, has small features.
V4.2 : -made the mid bolt tab larger, more robust and easier to print
-slotted the wire hole for the front fan

So you can fix 4010 or 4020 axial fans of your choice. With tool less push pins or M3 bolts. Built-in recesses for the M3 nuts (5.5mm wide across the flats)

-includes optional add-on part that goes under the hot end fan to complete the duct to get absolute maximum efficiency. leaving this as a separate part from the fang because it would prevent from printing it without support. Just glue it in place after
-Chimney at the right to zip tie your wires (prevents the wires from breaking at the heater cartridge base)
-Tiny hole in the front to put the allen key through the fang to access the rear middle bolt (this bolt is optional tho, 2 bolts holds it pretty tight already)
-Rear bolt is inserted from the back through the slot and needs an M3 nut to be inserted from inside the fang.
-STL for the front fan duct to prevent sucking every debris and filaments from the build plate. Prints without any support, just lay it flat on the fan flange. For installation you need the longer push pins (STL named "holder pin 4020 fan + duct")

The idea behind this project was to be able to use two silent 4020 fans. I used a sunon MF40202V2-1000U-A99 fan (bought on digikey for about 5$). I added a 330 ohm resistor to reduce speed and noise (brings down the voltage to the fan to about 18v).

No BLtouch mount yet, i'll see if i can come up with something.

Elias did a super nice install video of the fan on his ender 3 V2 if anyone wants to have all the details on how to install this.

3D printing settings

Prints without any support. Just lay flat on the top fan flange as pictured and you're set. The duct also prints without support, laying flat on the flange as pictured.

Ideally print out of petg, it is more flexible and durable than PLA but it does work out of PLA. Push pins are better made with petg too since it's more flexible. PLA is a little stiff for those and you might have issues to put them on.

Print with 0.4mm nozzle with 0.2mm layer thickness. About 20% infill works great

Yeah it has been a recurent comment that the microswiss clones were a little shorter than the stock or real microswiss hotends. That's exactly the reason for this update.

One of the tweaks I had to do to your model was make the holes adjustable to raise the height so there was more clearance from the build plate. Now I see your latest update has done just that. Lol! Thanks for that revision it will be helpful for others. I use the stock carriage with a microswiss hotend and found that since the microswiss hotend is a little shorter in height it was making the fang awfully close to the build plate. Problem solved now though... Thanks for the info on the LED hookups. I plan on just using the two leds down on the bottom to light up the printing area. So will use the buck converter and probably to the mainboard. Thanks again!

@Rivers: Thanks for your kind comment :)

Right now I have a buck converter down at the PSU and a wire coming up to power the LEDs at 3.2v.

My first set-up tho was a series of 8 small LEDs plugged in series together (8x3v = 24v) and plugged them straight on the hot end fan. So i had 6 LEDs inside behind the Briss logo and the two at the bottom.

I have downloaded and printed your ender 5 setup and love it! Had to do a few minor tweaks to get it dialed with my custom setups but other than that they are working flawless. Have it currently running on two Ender5. I printed the file that has the led mounting options on them but haven't installed any yet. If you're running leds on yours would you mind sharing where you're getting your power for them? Did you run wires all the way to your PSU or somewhere in between? I'm thinking about hooking the led wires into the mainboard on one of the spare ports. Not sure yet though. Thanks again for such a fabulous design, look forward to more!

Printed the prototype duct with grill to fit on my new ender 6 (different but similar to the ender 5) just to realize the duct interferes and would limit maximum travel... I'll need to come up with something else for these, maybe side feed duct. I will still upload it but i'll design something else for the ender 5-6.

I got really interested in the height adjustment slots and the duct grill! 👍

Luminat, adding slots for height adjustment, adding grill on duct, maybe widen the space between the two ducts a little for easier access, but nothing major. Someday a version that should fit with V6 hot ends, but this project has been on the back burner for a while, too busy with work.

Do you have any plans for additional changes to this?

Ohhh, ok! That makes sense now. Unfortunately all grills will make more noise than without, unless maybe doing a PHD on the subject. Thanks for your feedback, i'll add that to the to-do list.

The idea is to have a grill to installed in the inlet of the "40mm fan duct up.stl" part.
This duct is awesome and really protects the hot end fan from sucking debris from the bed, but the down side is that it is a collector where, if anything fall in, it will be trapped in and may damage the fan impeller without any notice.
I understand that it is possible to install a standard 40mm grill in the outlet of the part, but I imagine that something in the inlet will be safer and could even reduce even more the noise.
Another ideia is to have a new part "40mm fan duct up with grill.stl" for instance, where we will have a front grill embed in the part.

@Paulo, there is plenty of standard 40mm fan grills on thingiverse to chose from. I did include a fan duct for the front fan to avoid sucking stuff from the build plate.

Hello my friend! Nice model! Congrats!
Just bought it and I was wondering if it is possible dor you to design a grill to be installed on the hot end duct to avoid anything ro fall inside it and destroy the fan.
Thanks!

i use only one buck converter for the 120mm fan mod. I just glued it into a free spot inside the PSU (silicone adhesive). My hot end fans are all 24v so no buck converters needed here.

Thanks!
One more question, I'm also planning on doing the 120mm fan mod.
Where did you put all the buck converters?

Hi Normanu

Offset -44mm and -8mm

Just bought the file, thanks!
Can you confirm the offset for the BLTouch?

@TRBK, won't happen. Too much airflow and would cause bed adhesion issues. Guys have to turn down the 4020 already. Thx

hey could you do the noctua 6020 at the top?

You can try the ender5 facebook group or youtube tutorials. Pretty sure you will find what you need with those two.

OK cheers, I'm new to 3d printing and I'm trying to get hold of some basic settings for it for cura

Robshell no, i have an ender3 with microswiss direct drive

Are you currently running an ender 5 with microswiss direct drive

Yeah, supports are always tricky... And something that works for me might not work on your printer, depends on so many factors. I uploaded an image of the bracket in cura in the orientation to minimize needed supports and the support settings. This will only work if you have good adhesion to the print bed. You can make the brim wider or reduce the overhang angle or add custom supports to hold it better in place if needed. Hope it helps :)

Another question you may be able to help me with and thats on the bltouch bracket, I can't seem to get a good print with it. I'm using supports but when I remove them I'm getting a lot left on the print. Can you give me an idea on what settings I need to use please. I'm new to 3d printing and still having a few problems with settings

Thank you, I thought thats what I could see in the picture

Hi Rob

I think i just missed the file when i uploaded the model. Just put it up right now. File named microswiss DD spacer. Sorry about that.

I've made all the parts ready, I have ender 5 plus with bltouch and a microswiss direct drive. I have gone to fit this part I am unable to due to the extruder shaft hitting the top fan, is there any way you could design a spacer for the fan with a hole for the extruder knob to go through

Awesome, thank you :D

Right now i didn't make a BLtouch bracket that fits. But maybe some others already fit, i don't know 🤷‍♂️

Does a BL Touch still fit even if you havent come up with a mount?
