The model represents an adjustable wall mount arm for various VESA-compatible equipment (primarily displays).

Specifications:

Quads only topology, fully subdividable.

Units: Metric

Bounding dimensions (at full length, no elevation):
12 x 47 x 24 cm

Mounting standard: VESA-100 (100 mm center-to-center between holes).

Mounting holes diameters: 6 mm (VESA side), 8 mm (wall side).

The model consists of 8 objects (see disassembly picture in wireframes - numbered from right to left) with following properties:

1) WallmountArm wall-side base.

2) arm1 (horizontal rotation, constraints: +-105 degrees).

3) joint1 (horizontal rotation, unconstrainted).

4) arm2 (elevation control (pitch axis), constraints: -75 to +60 degrees).

5) joint2 (additional pitch control, constraints: -75 to +45 degrees).

6) arm3 (horizontal rotation, constraints: +-90 degrees).

7) joint3 (spin control (roll axis) - for, say, changing mounted display orientation from landscape to portrait etc - constraints: -90 to 0 degrees).

8) VESA100 mounting pad.

All objects are parented to each other from 8 to 1 correspondingly. All objects are grouped into single group for easier appending / linking.

Materials:

Two procedural PBR materials (PBR_Steel, PBR_DarkSteel) based on Principled shader, thus compatible with modern PBR renderers. No textures used.

UVs unwrapped.

HDRi environment map (Blue Grotto, public domain) packed in .blend for more realistic reflections, as well as put into supporting items separately.

All imagery is done via Cycles / Filmic (Base Contrast profile), no post-processing.
