Maybe Its a good idea to include a printed extruded couple like this one: https://www.thingiverse.com/thing:3360380

CR-10 Extruder Coupling
by bert_lz

I was wondering if you could make an alternate extruder bracket that accepts just the PTFE tube, not the fitting, for those of us who have converted to direct drive extruders?

What material have you used ?

In this I used carbon fiber infused nylon filament. I printed this on the Matterhackers Pulse XE printer with Olson Ruby Nozzle

Would PETG be strong enough ?

Yep! So would ABS, Carbon Fiber, and some nylon materials.

Comments deleted.

Is there any way to make this run with 3mm filament

If you wanted to, then you would need a whole new extruder gear, bearing, PTFE Tubing, extruder throat, heating block, and nozzle, all in would cost a lot of money, and an immense amount of research would be required.

Thank you for this thing! Thumbs up to you!

Thank you for the idea of running the PTFE tube all the way to the filament box!

can you please tell me size of the brass screw tube sorry I don't know proper name for it :( it the brass part that screws into this block and then tube slots into it ? I did buy some without realising the printer head side is larger than this one :(

Looks great, but will it work with the Ender-3? seems most any CR-10 parts will.. also as to what @SkynetDesigns said, the ender-3 also has an incredibly similar arm.

Just saw the Bed connector too.. what the hell? First not releasing Marlin source, now they are actually taking Thingiverse designs? I was just starting to like Creality...

I believe that I will work on the Ender 3. I don't personally have it but as you said they seem to be almost identical.

Note; re-read the Bed Thing Details.. apparently Creality did contact him. Gave him a CR-10S and an Ender when he agreed. Hopefully the same happened here, it is practically the same damn extruder... that said, is there any point in using this? Should I add PTFE?

Nope. Didn't receive a single word or got anything from them. Quite unfortunate. Anyways, I don't personally use any PTFE tube except for the bracket which helps for flexible filament but the extended arm does have a place for PTFE tubing. If you don't want PTFE tubing (it doesn't really help with flexible filament) in the extended extruder arm, then I suggest my other design. https://www.thingiverse.com/thing:2492903

Hey man... that is really lame, honestly, that they didn't reach out to you. If you'd like, i'll provide you some photos of the ender3's extruder and show you how closely it matches yours. The ONLY difference I can see is the end of the lever shifts differently. If I were you, I'd contact them and ask for credit/compensation. If you need help, please contact me about this. It will not be the first time I've encountered it and helped a person or community deal with a company like this. Don't back down. Creality is not some kind of basement gig, it's an international company.

I was going to upgrade to your part but...

Have you seen what the 2018 CR-10 come with? (not the "S" model)
Its no longer has the yellow extruder, its black, and looks VERY similar to your design.
I wonder if they "borrowed" it
Under your licensing i guess they could have

They also now ship with the wire strain relief from this site. https://www.thingiverse.com/thing:2186203

Creality CR-10 Strain relief bracket for heated bed cable

Hmmmm, very interesting. You could still probabaly upgrade to my part as that does not seem to have a hole for a PTFE guide tube. It is very odd as I have not received anything regarding to that.

Looks very interesting. Would you please post a few photos of the complete installation?

Yes. Check back in a day or two.

What is the mmiddle part for?! And where does it belong?

It is meant to hold a filament tube and the excess wire. Check the picture under the comment by MrJelle.

Where exactly is the filament tube holder supposed to be mounted?

On the screw right above the x-axis motor

I've printed a lot of these different "flexible extruder" designed off thingiverse, and they all have the same problem. When I screw on the tension/guide bearing it doesn't line up with the in/out holes in the design, it is too high! the tab coming out it much thicker then the stock one. I don't see a problem with the thicker tab to mount the bearing wheel, but the other holes need to be moved up so it's all in line again.

Unless of course this is a "feature" I don't understand.

Am I the only one with this problem?

I fixed this issue a couple months ago.

Just tried this and the problem is still there for me. The guide bearing sits noticeably higher than the holes, using CR-10S S4 stock extruder parts (the black one) with the bearing sitting directly on the PLA with nothing in between.

I had the same problem. I slightly modified the part with the roller. If you need, i can upload it.

That would be greatly appreciated, I'm in the same boat.
