hello, can i have the wall and bottom thickness for this file. Thx a lot

Due to the design of this cover, the CR-10 will not reach its full height.
The lead screw on the CR-10 is supported by a bracket on the top end. This bracket overhangs the extruder, so the cover runs into the bracket stopping the Z-axis short of the 400mm.
If you need to print the full 400mm.

What did you use to slice this? Also, what orientation should we be printing this? The little recess at the top seems to generate a lot of support that's hard to remove.

Just got my CR-10 yesterday and this won't fit over the trigger that takes the pressure off the feed line.

Me too. I took pliers and ripped off the section where the trigger is. I'll see if it fits on next time I do it filament change.

Printed fine, had to trim the right edge of the narrow slot because filament was rubbing on it, otherwise perfect.

Gorgeous design bro, love the chamfered edges and general style. I actually love the printed surface in this colour filament too. Good work :)

I printed this in ngen filament so I don't think it shrank. However the input side was a little off causing a squeaking noise as the filament rubbed the edge of the plastic. Then I realized I was having a really hard time getting the filament to stick to the bed and figured out it was the cover putting pressure on the tension lever allowing the gear to slip and under extruding filament. As soon as I took the cover off everything worked great again.

Hi, I like your design

It is a tight fit so it rattles a bit.
I'm going to remix this however to improve the cable management portion as well as allow a PFTE mount to route filament through there instead on the input side of the bowden setup.

Please upload your design!

Does the cover also keep the filament from rubbing against the Z-axis?

No it does not but it's a non-issue I have close to $1,000 of printing on my cr10 and zero issues with it rubbing don't worry about it

Great design, thanks for sharing. I just printed one flat side up. Didn´t need support.

Printing now. Printing flat side down with support. I'll report back how it turned out. Nerys - I'm surprised you can bridge that far and still get it to work. :)

That's a very short Bridge if your printer can't handle that bridge you just have to tune your settings a little bit that's all

no support is needed. print it in the orientation it goes onto the printer (open side down) and it printed fine with no raft or support.

how did you print the roof open side down without support? which settings did you use in the slider?

I just did it's a bridge that's all but it's a clean Bridge so the first layer or two are a little loose but it prints clean otherwise and works fine sometimes you can leave a bridge a little bit sloppy and you don't need to waste support on it there are plenty of layers there to retain the structural integrity

Does this completely cover the yellow printed piece that is there by default or have you reprinted that piece?

Yes it completely covers that plastic piece which is not printed by the way it's injection-molded

yes nice snug slip fit.

Thank you, will definitely be printing one when I get my CR-10.

Im printing one right now! Thanks!
