How can I make a hollow cube with a window

Hi. I am new to blender.
I want to make a hollow cube(4 cm x 4 cm x 4c) with inner thickness of 1.5cm.
And top surface, it has a 2 cm x 2 cm window.

I can make a cube with window, but i can’t make a hollow cube with a window on top surface.

Hi,

If you meant something like this below:

You can achieve this by using a Wireframe modifier.

  1. Apply a Wireframe modifiear to a cube,
  2. Change its parameters that will suits you,
  3. Apply the modifier,
  4. Create a top manually, go to an Edit Mode, select all 4 top edges and hit F key to make a face,
  5. Fit other edges manually to the right angle.

Here’s the blend file anyway:

Please Ignore the object inside the cube.

Something like this?

Yes, but the cube has closed surfaces except window on the top.

I got this:

Thank you for your kindness!
It helped me a lot and saved valuable times.

Try also this, I set the hole size to 2cm x 1.5cm x 4cm as you asked:

hallow_cube_new3.blend (808.4 KB)

P.S. I set the width to 4cm because it looks much wider on your photo, it is not about 2cm. The hole looks more like a rectangular instead of a square

Thank you again.
But cube size should be 4cm x 4cm x 4cm with all closed surface except at the top it has 1cm x 2cm window.

The cube should be hollow with wall thickness of 1.5cm.

I tried to change using your file but hard for me.

It is already 4cm x 4cm x 4cm

Yep, it is :slight_smile: Just check cube’s modifer that goes by the name of Solidify

Here you go:
hallowcubenew.blend (808.4 KB)

but if i measure the side, it’s 0.4m

Try this one

Also change your Length units from meters to Centimeters:

Hmm… something is weired.
Why is winodw at the top surface so small?
How can I change the dimension of the window?
It’s now 0.25cm

You need to understand how to work with dimensions by change them manually. I cannot give the exact result, but only the similar one:

Check this one, I made a hole with the dimensions you’ve been asking for:

All except thickness, as I see it, done correctly. If I set thickness up to 1.5 cm, it creates weird inner cube inside of the main one:

So I left it on 0.15 cm instead

that’s actually not going to work…

okay, so if wall thickness is 1.5cm, then you have 3cm of wall (remember, 2 sides)… this will leave you with a hollow area that is 1cm x 1cm x 1cm, before having your window added. since you have the window 2cm x 1cm on the surface … well, it’s twice as long as the hollow area in the cube.

did you really want the wall thickness at 1.5cm?

@goorman 's use of .15cm does fit the image better, and would leave plenty of room for the window even at 2x1cm.

That is why, as I have shown above, If I set it up to 1.5 cm it started looking kinda weird. I think it is better to have it on something around 0.15 cm.

aye, i kinda figured. :slight_smile: another possibility would be .75, which would allow space for window, and then the wall thickness .total. (for both sides) would be 1.5cm.

it may be easier if @Dhk instead specified how big the hollow inside the cube is (with the caveat it must be at least a 2cm cube to fit said window)

Thank you for your help and insight! @KDLynch , @goorman .
That’s right, my initial design was wrong and not based on real possibility

What I want to make is a hollow sphere with about 4 cm x 4cm x 4cm and small window at the top(1 x 2cm). Thickness of the hollow sphere don’t need to be 1.5cm on all area. It should be 1.5cm thickness on the bottom(opposite to the surface with window).

I want to 3D print it and 'll do some experiement with it.

0.15cm wall could be sturdy enough to 3D print?
