I want to build this thing, exactly.
I've created a cylinder and extrude it.
How can I extrude the ring outwards exactly 7mm? Or Is this the complete wrong way to do this?

Another way to do this is to first create a one-sided cross-section with the object origin in the middle. That way you can extrude with numerical input or even set the locations in the transform panel.
when all edge lengths and positions match, just use the Screw Modifier or the Spin tool to create the cylinder.
To me, this method is the most transparent. I have full overview over the shape and dimensions. I usually take my calipers and make a quick drawing on paper to have a reference instead of switching back and forth between object and computer.
It also liberates from the pretty much relative nature of extrusion. I could just measure the distance between the two rims and SHIFT-D the verts that distance apart. Lots of possibilities.
Calculate scale factor from dimensions
Consider you have a cylinder with diameter 20cm
(200mm
).
To extrude the selection about centre point, and to have a new diameter of
214mm
ES1 The 1 is arbitrary we can fix in the operator panel
The required scale factor is 214 / 200
or 1.07
. Can set the x
, y
and z
scale factor in panel. (Or ES1.07 and reset z
to 1.
Notice you can type arithmetic, 214 / 200
directly into the property.
