N900 Case Scans

These are scans of mechanical parts of the N900 phone. They are intended for designing mechanically compatible elements, such as the Neo900 spacer frame.

The available groups of scans and pictures:

The inside of the bottom shell: with stylus, without stylus, and assembled (i.e., with battery, cover, and stylus).
Elements of the keyboard: key mat (top only), keyboard frame (inside only), both together (only pictures).
The top of the fully assembled base, without keyboard.
The main PCB: top with daughterboard folded away, bottom with daughterboard on top or folded away, and the daughterboard alone, top and bottom.
The display module: the inside, with the sliding mechanism in the closed and in the open position.
The rear side of the device, with the battery cover open and the battery absent or present.

Scans are stored in the following file formats: PIX, the text format of Dr.PICZA project files, and STL. Clicking on the thumbnail image will show a larger version of the 3D rendering, generated with MeshLab.

High resolution scans can produce a large amount of data. If a file is 100 kB or bigger, its size is indicated.

Bottom shell, with stylus

The bottom shell is the main structure of the N900 case. The following two pictures show it with the stylus partially inserted, the way it ended up after the 100 μm scan. Note that the scans do not quite reach the bottom of the shell and some deep areas that are closed therefore appear to be open.

Bottom shell. Inside.

Note: in the 100 μm scan the scanning head partially pushed the stylus out of the case.
The stylus therefore appears to be distorted.
Also note that the scans did not go all the way to the bottom of the case shell.
Some of the holes therefore simply represent a floor that has been out of reach.
The "Bottom shell, assembled" scans below are more accurate in this regard.

Key mat

The key mat is an assembly consisting of the key caps mounted on a rubber sheet, stabilized with a sheet of steel. Note that a small piece of dirt was stuck between the X and C key, and was picked up in the scans.

Keyboard frame

The keyboard frame is a fragile plastic structure that is attached at the top of the bottom shell and holds the keyboard in place.

In Neo900, the keyboard frame will be integrated into the spacer frame.

Keyboard frame. Inside.

Note: the keyboard frame features little "horns" that snap into the bottom case shell.
These horns and the narrow (about 1.6 mm wide) plastic strip they attach to easily bend away from the scanner's needle and are thus only partially visible in the scans.

The bottom of the daughterboard is covered with a soft foam that confused the scanner and caused the ragged edges in the X+ direction.
