Bowden X-Carriage Mount for E3D V6 [V2] by Prometheus3D Jan 8, 2017


Please support me by donating or by leaving me a tip on thingiverse, It helps a lot


Make sure to post a make if you print one!


17/02/2017 - Added a BlTouch sensor variant.

13/01/2017 - Added an 18mm sensor variant.

08/01/2017 - First release.

What Is It?

If you are upgrading your Prusa i3 hotend to the E3D V6 or an equivalent hot-end with the standard groove mount, you will need some way of mounting it to your x-carriage. The mount attaches to the x-carriage using the same four holes mounting system that is used on the Prusa I3 rework 1.5 kit, so you will need to print off a compatible x-carriage.

This design uses a clamp so your hotend will stay firmly in place and won't wobble around.

More features are on the way including cable chain support and dual extrusion options. Please comment on anything you want me to implement and let me know of any problems that you are having with my design.


Parts Required

4 x m3 25mm screws
4 x m3 16mm screws
4 x m3 20mm screws
10 x m3 nuts

E3D Hot end (or clone)
30mm fan
50mm radial fan
12mm inductive sensor (or optional 18mm sensor)

Post Processing parts

I designed the parts so that they shouldn't need any cleanup. So just print the parts and you are ready to assemble it.


1) Firstly use 4 x m3*25mm screws and 4x m3 nuts to secure the main body of the mount onto your x carriage.

2) Use 2 x m3*16mm screws and 2 x m3 nuts to clamp the hot end onto the main mount using the printed clamp part.

3) Use 2 x m3*20mm screws and 2 x m3 nuts to attach the 50mm radial fan onto the printed clamp part.

4) Use 2 x m3*16mm screws to attach the 30mm fan to the left-hand side of the hot end.

5) Use 2 x m3*20mm screws and 2 x m3 nuts to attach the fan duct to the printed camp part just below the radial fan.

First Thx allot for your work as you wrote I will add my wishes in the comments

  1. Cable Chain Support
  2. Dual Extrusion if possible that both extruders can reach the whole bed and auto level support
  3. Maybe an X Carriage that either has holes for the bearings or has integrated printed bearings so we can get rid of the cable ties
  4. a hypercube version
  5. 40mm Fan Adapter

Thank you for your suggestions, I'll definitely get to work on some of them! Cable chain support will hopefully be coming soon, and does this design not fit the hypercube already?

Don't know didn't build it yet :-) Just thought to list it if it doesn't

again thanks allot for this

No problem :) I think it does fit the hypercube as it uses the same hole mounting pattern as mine, it also fits on my own printer that I have designed which is quite similar to the hypercube.

Hey, can you please post the offsets and travel limits ?!

Very nice design. Have you done a design - or could you do one - for the pl-08n sensor? They seem to be gaining in popularity

Thank you! I have not done one yet, but I could look into doing one, it may take a little while unfortunately as I am quite busy.

I look forward to it - I can't wait to put this on my remix wilson II. I have to be patient and wait for the parts from China.... I was going to get another bltouch, but saw the pl-08n on youtube and I want to go that route. Thanks for replying to my request

No problem, I recently bought a BL touch clone from China and ill be testing that. Do you know what the advantages are of using the pl-08n over other sensors?


PL-08N sensor has a longer sensing distance and you are supposed to be able to use this with glass - and don't forget cost. Also, I looked at the 3d touch sensor - is that what you are looking at?

Has anyone printed this whole thing in PLA? I have all the parts printed and put together but im afraid the heater block is too close to my PLA carriage. I added a washer between the heater block and the heatsink on the e3d V6 to space it a little bit more. Anyone know if that was necessary?

Very nice design.
When you take a look at it tomorrow, could you maybe make a version where it is possible to use M4 screws to mount it to the x-carriage? Most x-carriages i have seen uses M4.
If you correct the issue with the alignment and makes a version of the BLTouch with M4 to mount to x-carriage, and make a hole to adjust the BLTouch between the two BLTouch mount screws, then i will be very happy and surely post a make (:

Thank you, I will be sure to make an m4 alternative. The reason that I went with m4 initially is that I saw no need for m4, and most of the screws in my printer are m3, as most of the carriages are m4 I'll make m4 variants

Grelt! Thanks!

I have looked at the model and it turns out there are more problems than I originally expected, I don't know at what point the model broke. Due to me being busy last night I was not able to fix the model, i will take another look later tonight.

Sorry to hear that - I hope you can fix it since it is a very nice bowden mount (:

Thank you for your patience! The Bl Touch mount with the m4 holes and the hole for the adjustment screw should be up now, let me know if it works.

It looks very nice!! (:
There is just one little thing now. The distance between the M4 mounting holes is a little bit off. They are a little bit too close to each other..

I left the distance the same, so I may have the initial distance wrong, what is the distance(mm) between the holes on your x-carriage.

As far a i know the distance between the center of the holes are 23mm in both directions.

Sorry about that, it should be fixed now (:

PlougDK - in reply to Prometheus3D

Thanks man!
I can't see the fixed version yet. Maybe it has not been updated, idk. Btw, the size of the holes should just be 4mm. They do look a bit larger..

it should be up, I did add a small tolerance to the bolts go through the piece without threading in.

Could you do this last adjustment? Making 23mm between the M4 holes instead of 22.5mm and making the holes 4mm and not 4.2mm? It is so close to perfection now!
Thank you in advance (:

I just downloaded it and measured the distance between the holes - It is 22.5mm and the holes has a diameter of 4.2mm. I got a printer that is very accurate and thus i dont need the tolerance. If the holes come out too big, it can be a problem. Even if the holes come out a little bit too small, the best solution (imo) is just to use a drill to get it to the 4mm.

main18 and clamp do not seem to line up properly at the rings that do the clamping is that normal? my E3D V6 has not arrived yet or i would test fit before asking.

I have fixed the alignment issue now.

Hmm I think that may be an error, I'll take a look at the model tomorrow. Thanks for posting the picture, I now realise what everyone was going on about.

Hello, I have a small problem, there is an offset between the base (bltouch) and the clamp on the side of the clamping rings e3dv6.

Can you help me ?

Thank you

I have fixed the alignment issue now.

Are you talk about the parts not lining up? as I am aware of this issue and will fix it tomorrow.


anyone using it with the cable belt for the x axis before I get my self on cad ?

What is the offset of the proximity sensor in the 12 mm variant?

I have fixed the design issues, if you want I can pass the files in step format

Are you talking about the issue with the original e3d dimensions? And I'll need to make the changes myself in fusion anyway. However I probably will not be able to fix the issues for a few days as I am quite busy. It would be great if you could pass me the step files as I could temporarily replace the downloads until I fix mine. Thanks for your help.

I printed it today - very nice design.
Unfortunately it doesn't fit to the original E3D V6 :( The heating block is a bit larger on the original one, so the block is pushing against the fan duct. Did you use a clone?

Just forget what I wrote :D Just change the direction of the heater block and the cables to the left side and it fits.

Sorry it took me a little while to respond, and I did use a clone myself. However I have now brought an original lite6. I will get to work on making my design compatible with the new block and silicone sock.

Hello, the x-carriage that I use with my mount is the prusa rework 1.5 carriage, and it can be downloaded from:

Hope this helps.

Hey Sir,
Is There a way to get a m8 (6.8mm, 7mm would be great) Sensor hole?


I have posted the 8mm sensor variant, let me know if it works!

Is it possible that you send me the clamp file ? Or adjust the fan blower. Because the fan sits just a bit too high and hits onto the heater block. So it doesn't heat up... Actually just the "HOT!" Part is good too

I'll put up the files, what file format do you need?

Thanks for the upload buddy :) !

.prt would be nice :) I'm using NX. I'd just like to modify the height of the fan duct since it'd be a shame if I printed this one for nothing haha :D You can also send it to me via email if you don't want to publish the files.

I really like this design. Is it possible to print this in PLA or do I need to print this in ABS or other material?

Although the duct sits relatively close to the hotend, I printed it in pla and mine seems fine.

Just printed and noticed the two clamps are uneven...

Sorry about that, I'll change that on the next update, it's because the clamp was too loose, so I took a bit off the bottom so it gripped the hot end better.

Hi! Awesome design!
Just wondering on the update. I agree the two clamps are not even.

Thank you

is it possible to get a better rendered image - the 3 dark ones are hard to make out - where does the last piece go (with the "HOT") cut-out

Feb 16, 2017 - Modified Feb 16, 2017
Prometheus3D - in reply to Goldie1471

Sure , I'll put one up

Much clearer - thank you

No problem.

And the piece with the "hot" cutout screws into the front of the clamp ,take a look at some of the makes.

Is there a way you can make a 40mm fan fit :) ? The 30mm is quite noisy...

I will have a look into designing one, however it may be a bit bulkier.

i'ld like to have a design with an 3dTouch or BLTouch Sensor. Would this be possible?

I'm not familiar with the bl touch, but I'll try to find some dimensions and look into designing one.

thanks that would be awesome. I think the Indiegogo campaign website delivers most of the dimensions.

I have posted the design for the BLTouch, let me know if it works as i haven't tested it,

Thanks, thats awesome. i printed it on saturday right away and the measurements are working.
Although it would be helpful to have another opening at the top for the adjustment screw.
Have a look at http://www.geeetech.com/forum/viewtopic.php?f=27&t=18263

Some additional improvement i would suggest.

  1. The four holes for the mounting screws to the carriage could be a bit larger in diameter for the screwhead to remove tension.
  2. The outer sides of the mounts for the clamp could be a bit wider to enhance the stability.

Thanks for you work.

Thank you for printing my design, make sure to upload a make! I had no idea that there was an adjustment screw there. I'll upload a new version soon with the access hole. And thank you for your suggestions.

It would help people if you could display the sensor offsets please

Sorry for the long reply, the offsets should be x30mm y6mm for the 12mm sensor.

I love this design! So simple, clean and no unnecessary weight. Will print this and the carrige ASAP and try with my A8!

Thank you, the goal with this design was to be light and compact, i have also recently brought an anet a8 and I hope to install this carriage on to it. Make sure to post a make and let me know if there is anything I can do to improve it.

do i have adjust or configure anything if im using skynet firmware?

Sorry that I am late replying, and I'm not very familiar with skynet firmware. You shouldn't need to change anything as long as you are using the same bed leveling sensor and extruder gear.

Jan 19, 2017 - Modified Jan 19, 2017

I really like this design! It is compact and contains all the stuff you need such as both fans and the level sensor.
The only thing I am a bit worried about is if the nozzle gets too much air from the fan supposed to cool the model. Have you seen any such problems?
But I like the duct too, many of the remakes for fan ducts are so complicated that hardly no air is coming out of those tiny holes.
The fan duct can be redesigned while keeping the rest intact, thats another good design.

Maybe I will do a remake with some LED spots on the nozzle...

Top notch!

Thank you for your comment, that was the goal with this design, the first x-carriage mount I ever printed was complicated and bulky with large fan ducts on either side. I borrowed the compact layout from the Prusa i3 mk2 as it was really efficient. With regards to the fan duct I have not experienced any issues, my hot end seems to maintain a stable temperature, let me know if you experince any issues with the fan duct and ill be happy to help :). Im always improving the fanduct to get optimal airflow. And feel free to make a remix. I'll get around to releasing the cad files soon.

I am also quite new to CAD and have taught myself the basics to fusion 360, I am slowly teaching myself, however, there is still a lot that I don't know. So what sort of file types do you want me to share?

The third file with the text "HOT", that model is supposed to direct the flow from the fan to the model being printed?
And for hotend cooling there is a 30mm fan mounted from the side on part 1 and 2?

Prometheus3D - in reply to matsekberg

Yes that is correct , I'm sorry I've just been busy the last few days, I'll try to get some instructions up tonight as well as the 18mm sensor version.

Could you make a version with 18mm sensor? Or publish the CAD-file for others to modify?

The 18mm one should be up now, I didn't know the dimensions of the nut, so I looked them up online, let me know if it fits correctly. And I'll release the CAD files soon as I need to tidy them up a little bit.

matsekberg is right, You should remove this mesh from fan tunels

I'll print one tonight.
Another idea would be to skip the grid "obstructing" the flow of the 30mm fan. At least on the fan side.

Thanks for the suggestion, I don't know what I was thinking when I put that grid there. I have since removed the grid obstructing the fan.

Jan 12, 2017 - Modified Jan 12, 2017


This works with Anet A8 printer?

And its good idea to put more info about this, like what size sensor it is, what offset for it etc.

Jan 12, 2017 - Modified Jan 12, 2017
Prometheus3D - in reply to Draxan

It should work with the Anet A8 as long as you print this carriage (https://dl.dropbox.com/s/hhq0nspszbusbcm/X_Carriage.stl?dl=0) ,you'll also need to purchase 4 x LM8UU ball bearings as I'm pretty sure that the Anet A8 comes with SC8UU bearings.

And I'm sorry, I've just been busy the past couple of days, I am planning to add a lot more info about this tonight. :)

Anet A8 using LM8UU bearings so its the same :)
