This is an adapter for Single or Double E3D V6 hot-end for Replicator 1, 2 or clones. Reused most of the parts of original makerbot including thermocouple, heat cartridge, cooling fan, filament blower. Will work with stock x-axis carriage, but I suggest the included carriage as it provides better clearance.

Print Settings

Printer Brand:






0.2 (Normal)




1) The hot-end sits higher then regular hot-end, this was necessary for the cooling fan to be able to coll the entire heatsink, also do use the air-flow tray to direct more of the cooling fan air across the heatsink and not down into the nozzle.

2) Hardware used:
[clamp screws: single: 2x M3 35mm, double: 4x M3 35mm]
[fan: single: 2x M3 12mm, double: 4x M3 12mm]
[filament blower: 2x M4 20mm]
[filament-tube hold to blower/cable hold mount: 1x M3 12mm]

3) !! Do notice that the clamp screws DO NOT go trough the cooling fan they are not a match and is by design, the only screws holding the cooling fan go at the bottom of the fan and are 2x M3 12mm.

I have got little problems with your fan duct . Is it possible to use this duct ? Does it fit with the e3d ?

Improved Rep 2 Fan Duct found on #Thingiverse https://www.thingiverse.com/thing:51426

Improved Rep 2 Fan Duct

I am not sure if it will work, should give it a try... if I remember correctly the e3d is larger in diameter but shorter in height... you might have to mod that fan duct a little, position is the same, I used the same alignment (X,Y) as the original extruder with respect to the X tray.

A fan duct for pla would be very good :-).

You did a very good job with the e3d mount . Thank you .

What kind of extruder do you use for this ?

Is was design to use the original or any that will fit the regular makerbot nothing special.

I like the design but I want to use Titan extruder , is it hard to adapt ?
Do you have cad files to share ?

Hi, I included the STEP files which these can be easily loaded on other CAD software like FreeCAD or OnShape. The files are in the compressed file "e3d-v6-hotend-mount-step-files.tar.gz"

Great , thank you

I'm about to start printing this for my Replicator 1. I'm looking at the list of files and am wondering what the difference is between e3d-single-filament-hold.stl and e3d-single-filament-hold-pc.stl. What does "pc" mean?

Is the hold version when using a pneumatic connector (pc) for the feeding tube.

What are the dimensions of the hole? What size and type of pneumatic connector should I get?

What did you do about the extruder stepper hitting the top of the printer?

The stepper doesn't hit the top of the printer, see pictures at the end you can see my Makerbot 2's extrude at the home position and it has plenty of room. Can you share picture where the stepper hits the top of the printer?

Nice work Wilhelm, this is just what I'd been looking for, I will have to try on my R2 too.... ;-)

For the moment I have tried this on my R2X; as there was no double tray, I stretched the single tray, found out the dimensions for the double mount and airflow weren't exactly the same with this new tray (which was also 0.5mm too short, first time round, between the bars), re-touched the new double tray and airflow to fit the double mount, and then printed everything in PLA - mistake! PLA parts in the R2X does NOT work; I did this as I was in dire need of something better than my original R2X extruder setup, and hoped to print out an ABS version before this one melted out of shape within the 60-70º chamber of the R2X... didn't get even as far as 1 part before it deformed - thankfully I have some N-Vent so I'm currently re-printing in that - it should last a bit longer, hopefully enough to make up an ABS or BluPrint version!!

I'll try and get the files I made posted this week latest, (only STL I'm afraid, I used Sketchup to make the adjustments), and link them to here ... I will also make a quick adjustment to the filament cable holder, as the cable harness in the R2X is thicker, and ideally positioned a bit further back... I understand you don't have a R2X, so what you did do for the R2X is great!!

Great work, you saved me making this from zero, so thanking you a load ;-)


Hi Andy,

I am happy you found these useful, BTW I do have another design for the trays themselves. The reason I made these single trays different is because that E3D hot end needed little more room then the original tray, but the double trays should work . Take a look hope fully thay can help also your designs shoudl improve and give everyone more options ;) double trays here http://www.thingiverse.com/thing:1533955


X axis carriage (single and dual) replacement for Replicator 1, 2 or clones (lm8suu and lm8uu)

ohhh! If only I'd found those earlier, this would have saved even more time!! Please edit the title/tags and add R2X as well!
I think I don't need to upload any new design, your's are actually better than mine ;-)

Only one point which I will also add to the http://www.thingiverse.com/thing:1533955 page, the size of the carriage would seem 0.5 mm too narrow (as the one here is, although I did use the single and stretch it)), although it could also depend on the material... I continue over there...


PS the cable holder part would be better with larger holder for the cable harness, as there are more cables in the R2X! Maybe also a bit further back... ;-)
