Anybody has an idea to close the top of an Ultimatker Style 3d printer so that only the bowdentube is out and the camber is fully closed, something like a plastik foil that can move around? i want this to be as flat as possible.
I need something like this but in 4 directions

I am afraid you will end with something more traditional: https://ultimaker.com/en/community/21181-cover-kit-for-ultimaker-2-and-ultimaker-2

Yes somthing like that but this is way to havy I an in the process of building a 3d printer with the lightes printhead possible
I own a BCN3D Technologies Sigma with a similar upper layout. The best looking enclosure for the top I’ve seen is a blow-molded bubble. You are requesting flat as possible, so that idea does not meet your requirements.
The accordion you show is common for machinery with an abundance of power. Having a similar device on a 3d printer would put additional forces in areas for which the printer was not designed. Unless the upper cover was electronically controlled, I think adding resistance to the hot-end assembly might result in less-than-ideal prints.
If you don’t reject the bubble idea, it falls into the DIY category as well. One cuts into a piece of mdf or plywood an outline to match the bottom of the bubble. The plastic is sandwiched into the outline piece and a flat base with a hole in the center. When inverted and heated, air from almost any source is forced into the bubble. Due to the large vertical change required for the printer top, one would have to have a thick piece of bubble plastic, perhaps 2-3 mm.

The above article is directed to human powered vehicle builders who want the lightest possible weight. A bubble for the printer need not be minimum weight, hence the recommendation for thicker plastic.
Stratasys uses same kind of bellows(correct term?) in their machines http://i.imgur.com/fxGDOh.jpg
I watched most of the iris cover video, especially at the end when it is operating. To require the hot end assembly and cables to move that much mass while it prints has to impact the print quality. The link that Tomas Vit has provided shows a more angular approach than my suggested bubble form, but certainly a better answer than sliding plastic.
@Fred_U I have already seen somthings that are on top but this is the thing I dont want
Consider the iris cover concept but use extremely thin material such as that found in binder covers, usually about 0.5 mm thick to keep the weight down. One does not have to have such thick plastic to retain the warm air. There may be some droop to the thinner plastic which might require a different design than the iris video shows, but perhaps with some modification, thinner lighter material will do as your require without putting excessive force on the hot-end assembly. Consider also to apply a silicone based lubricant to the plastic to further reduce the forces need to move the parts.
why flat? Is there a size constraint? Can’t you just put the whole thing inside a larger flat box and call it a day?
@Tom_L no I am building somthing that woorks good but also looks good, I just want the bowdetube and the clear pvc tube that I have to stik out of the top and the front must have 2 glasdoors, this is my curent design but I want the top just to the green line because 70x47x47 cm is too tall

Why is that too tall? I’m not criticizing, I’m just brainstorming and trying to understand the parameters.
Here I have drawn it for better understanding, hope thise helps

it really doesn’t. I understand that you want to stop the air from flowing through that space, I don’t understand why there’s a height limit.
Just for the look, I want to paint the complete thing white with alumium corners and glasdoors, have been planing this thing for half a year now but I just need the top cover thing before I build it
Your best bet is to just build it taller than the build volume. You’re not going to find a reasonable way for the bowden tube to pass through a solid cover, you just have to enclose the space. You can make it squared off to match the ultimaker shape, or it could be a hemisphere or slanted sides/front, depending on what looks better to you. It could be transparent and easily removed completely or solid to match the frame with just a pop off lid. It doesn’t have to be very tall, just enough to allow unimpeded movement.
No thats the point, compact as posible it has to be symmetrical on the top and bottom, nothing sticking out exept for the bowdentube
yeah, you’re being ridiculous.
Just got an idea, gone try it right now out of paper, gone post my results here
