• all parts labeled “reaction wheel (RW)” (two bases, two walls, two windows);
• board with the reaction wheel (RW);
• universal board with a soldered cable for connecting to the reaction wheel (RW) unit;
• fasteners (screws with a cylindrical head M3x6 - 4 pcs.).

1) Install the reaction wheel (RW) board on the lower base (labeled: RW↓), fixing it with M3x6 screws with a cylindrical head.

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

3) Fix the two windows to the bottom base. To do this, guide each window along the guides in the walls to the base and snap into place.

4) Attach the top cover to the assembled case. 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:
