Summary

Extruder dust cover for the stock extruder of the Creality CR-10.

Features;

1) Dust cover that allows you to still release filament while in place
2) Cable holder
3) Filament guide to avoid filament touching the z lead screw (requires piece of PTFE tube fitted as shown in the pictures)

This is designed so if you really need to you can remove it while printing, but you would need to pull the PTFE guide tube slightly out the first holder so the filament can slide through the slot. I don't really know why you would need to do this since you can swap filament without removing it, but it's there just in case :)

No supports needed, just print it top face down (stl should already be orientated the correct way). If your printer suffers from adhesion problems you may need a brim.

Thanks for looking, hope people find this useful!

Be carefull dose not fit to the new CR-10 versions with the black color filament extruder only fit to the yelow ones

I should have paid more attention before printing but my extruder does not have the yellow lever. My CR-10 has a black lever which is a different shape. This cap does not fit over top of my extruder. :/ Oh darn, I'll have to print something else. ;)

Any chance you could easily make a modified version of this that adds a 90 degree upward sweep elbow on the filament input side for those of us using top-mounted spools? I tried to figure out how to do it myself, but was unsuccessful.

I have modified this to include a hole in the cable-holder, so that a cable-tie can be inserted and hold the cable in place. I've also modified the center hole so that it could accomodate the "pointer" as shown in the pictures.

nice design. I had to drill the hole bigger so it would fit.

Thank you very much for that design!
I've a question : what do you exactly mean when you say that there's no reason to remove the filament when you change color?

This is a really good quality part! Thanks for sharing! <3

graham01, I absolutely love your cover design! I would like to use your cover with the flag found here: https://www.thingiverse.com/thing:2564007. Are you able to redesign the opening such that it is large enough to incorporate the flag? Thanks!!

CR-10 Extruder Flag

Thank you for sharing this, it does just the job

YOU ROCK!!!!!!!!I have a hobby shop and people track in a lot of dust and debris this is super helpful and it went rite on and it has been keeping the area clean.
As soon as I catch up on my bills I will tip you. Thanks again.

Really glad it helped you, thanks! :D

I would like to see the hole for the stepper made a little larger so i could put an extruder spinner on it.

Hey this thing is amazing! One small problem...My extruder is now clicking with the cover on. Any idea why? I took it off, clicking stopped.

Thanks! Yea its just the tight tolerance of the motor shaft through the hole, mine did it too for a while but it wears in.

I lifted the cover just a couple of mm's, and problem solved, still fits nice and snug, no more clicking! Might take it off again and sand down the ceiling of it. Thanks!

It would be cool for this to have accommodations for a filament wiper of some kind. I know the PTFE tube has pretty close tolerances, but something to really clean it would be cool.

My Z axis srew will be blocked by this part.

Will or does? Have you tried? This is designed to go around the lead screw and not touch it.

Sorry for bad english. it does.

Is that even using the new version (r3)? Can you post a pic somehow, in the facebook group maybe?

It was r2 which I printed some days ago. r3 works fine. Thanks!!

My lead screw rubs on this. Any chance of widening the part near the leadscrew?

Damn sorry to hear that, mine was pretty concentric and had a nice gap around it, I guess it needs a bit more tolerance though. How much more gap do you think it needs?

Could try increasing the diameter by 1mm?

I'll see what I can do, thanks

Just updated it to r3, should have 0.8mm more clearance around the lead screw now. I can't test it because my printer is busy, so please let me know how it goes.

Thanks, i'll run a test later

I love this design so much. This should be the new gold standard on "what to print when you get your CR-10" lists. Thank you!

Printed one as soon as i saw it, very robust, much better than others I have tried. I did rework a tiny bit to make the top thinner but only to help speed up the print. very well designed.

Is that the shaft with the gear sticking up? If so I'd put a little "white out" on it so I could see it turning. This might be a good candidate for clear PLA.

Yes the shaft sticks of the stepper sticking through the top, it was made like that for 2 reasons, 1) to reduce print time and plastic (otherwise it would need to be a lot taller just to cover the shaft) and 2) so you can observe it turning. Yea a little mark could be a good idea :) Thanks!

Thank you~ Your design is very helpful!

Thank you! My last cover had to be removed each time I changed filament, which is quite often.
