Summary

My design of a modular hotend bowden mount.

The Hotend is very easy removable.

It is enough space left for an auto-bed-leveling sensor or any upgrades.

You need:

  1. variant
    3x 30mm fans

  2. variant
    2x 40 mm fans
    1x 30 mm fan

1x COB-LED (36x26mm or smaller)
1x XT60 or MPX connector
and some M3 screws

All threads are cut directly into the ABS. You need a M3 thread cutter.

Designed for E3Dv6 hotend.

The 30/30/30 fan duct part is not easy to print. I recommend to print with support.
The 40/30/40 fan duct is splitted for easier printing.

Updates:
27.08.2015

  • added clamp for MPX connector
  • some minor change to rework_adapter, now v1.1

20.09.2015

  • changed X-offset at the rework_adapter, now v1.2

02.10.2015

  • many improvements at the rework_adapter, now v1.4
  • added cable_mount_v1_0.stl

11.10.2015

  • new fan duct design for 40/30/40 mm fans added. Duct is splitted for easier printing.

19.12.2015

  • MPX clamp v1.2 added

I designed it for my P3steel, but it will fit on any printer that use the rework X-carriage or same screw distance..
Best use with my X-axis carriage: http://scheuten.me/?p=441

Hi Lars, a question for the MK2 version of your hotend mount - the BOM lists 2x axial fans but the fan ducts look like they're designed for radial fans, is that correct? Thanks!

Clear enough, sorry I didn't find that page on your blog. Thanks!

Is the blue tube for wire support?

Hi, your designs look really well made, great job. How can I mount this directly to the e3d v6 heatsink?

I really like your designs, can you make a modified version fot th e3d clone?

?

If it is a clone ...

The E3D v6 hotend from china has a slightly different diameter

All of the clones ive been getting have been the same size as the original. What diameter are yours?

Hey toolson,

why aren´t there holes for the molex connector in your newest adapter? And i also don´t understand the bowden_mount_e...

...oh i see you don´t use a xt60 anymore. What kind of connector is it?

Hi
How do you have screwed your fan on? there is no screw nut??

I have cut the thread in the printed part.
You can use a panhead screw for wood instead.

Hey,
where to get the colored PTFE tube?

Hello, this is simply awesome but how in the world do you power all three fans? I've printed off everything, just waiting for my two 40mm fans to come in the mail and I'll post my make.

Is this even possible with a Ramps board?

connect to heatsink fan to always on power (I loop mine out of the 12v input terminal), and the print cooling fans go into D9 (double check that). D9 can be controlled with g-code, so the print fans dont run on the 1st few layers.

Sure. Connect the two on the side and you have just one connection fpr the nozzle cooling. The one on the back should be always on.

Hi, I like your hotend.
For the led light have you used a resistor, and what wattage is the part?

The COB LED is for automotive use.
That's why no resistor is necessary.
Don't know the wattage at the moment.

I guess it does't heat up too much ? and is it glued? Thanks

It is positioned in the cooling air flow. But that is not really necessary.

Yes, glued with Epoxy.

Thank you, I think I'll print it

Hi! there's quite awsome hotend you've made here! thank you for sharing. I need to lower my hotend due to new mods of my printer and I was wondering if you can make the adapter to be in the bottom side, like the skrew holes for the carriage to be in the top side of the hotend adapter. Or, if it's too much trouble for you, can you upload the files of the adapter? I printed all of your modular bowden hotend adapter and works great! I don't want to lose the setup to switch to something else...
Thank you very much!

Done.

You printed all of my adapter parts? I cannot see them.
Please share your makes.

make = contribution

Thanx! I will print it out and post all the makes :D

This is AWESOME! Any chance you plan to make a dual hotend version?

Thanks!!!

Still hoping for a reply :)

Great design, really. But i have a chinese j-hotend, the clamp does not reealy fit. do you think you could a a clamp for these cheap, widespread hotends? it would be really nice...nevertheless great thanks ..

You need only cut 4.1mm from e3d_bowden_mount_b.stl via Slic3r.

Diameter of the heatsink is different too. 25MM on chinese hotends I believe

looks awesome, just 30mm fans are hard to source here, while 40mm are plenty available. Do you have an induction sensor mount planed?

40/30/40 mm fan design is now available!

There are 40mm to 30mm converters in thingiverse. But I agree a native 40mm fan version would have been cool.

40/30/40 mm fan design is now available!

Dude, you're awesome! Only problem is I already bought 30mm fans :( Oh well.. I'll use 40mm in my next build.

Hi, a little suggestion here.
For the heat sink cooling fan, maybe a round hole on the carriage will make a better air flow.

Wow.. this is almost exactly what I was looking for my P3Steel ever since I built it. Just did not have time to do the designing myself. Would you mind sharing your source? I would love to make this to work with 40mm fans for cooling the print, since I have a few of those laying around.
