• all parts labeled «(RW) 3D»(two bases, three walls, three windows);
• reaction wheel (RW) board - 3 pcs;
• cable for connecting reaction wheel (RW) boards – 1 pcs;
• fasteners (M3x6 cylinder head screws - 14 pcs.).

1) Install the reaction wheel (RW) board on the lower base (marked: RW 3D ↓) (the side connectors are soldered on the board), fixing it with M3x6 screws with a cylindrical head (4 pcs.)

2) Install the second «reaction wheel (RW)» board on the lower base (marked: RW 3D↓), fixing it with M3x6 screws with a cylindrical head (4 pcs.).

3) Install the side wall on the lower base. To do this, position the side panel projections with the holes in the base and snap into place.

4) Attach the window, using M3x6 cylindrical head screws (2 pcs.)

5) Install the side wall on the lower base. To do this, position the side panel projections with the holes in the base and snap into place.

6) Attach the reaction wheel (RW) module to the side wall using countersunk screws M3x6 (4 pcs.)

7) Install the side panel on the bottom base. To do this, position the side panel projections with the holes in the base and snap into place.

8) Fix the window to the lower base. To do this, slide the window along the guides in the walls to the base and snap into place.

9) Attach the top cover to the assembled body. To do this, position the cutouts on the top cover and the protrusions of the two walls and two windows and snap into place using force. This is how the assembled «reaction wheel (RW)» module looks like:
