Assembly

Step 1

Insert the sliding bars into the cube and make sure they can move up and down freely.

Step 2

Attach each side panel to the sliding bars and the cube in either one of the orientations pictured above using the connection pins and rotation clips.
The pins and clips are inserted into the holes by bending them slightly.
Assembly of the side panels is easiest when the sliding bars are in the lowest position.
Make sure everything moves smoothly.

Step 3

Attach the top of the cube to the bottom using the connectors.

Step 4

Put the top plate on the cube and snap it in place.

Step 5

Attach the cube to the lamp socket and insert a light bulb.

Step 6

Attach the bottom panel to the sliding bars. The sliding bars should be in the lowest position and must be bent slightly when assembling to snap into the holes in the bottom plate.

Step 7

Open and close the lamp shade and see if it holds its position or if it yields to gravity. If it can hold its position at any point you are done. Otherwise you will need to print a set of brakes and brake holders.
Start with printing brake_1mm and move towards thicker brakes if needed.
See Step 8 to insert the brakes

Step 8 (if needed)

Insert each brake into a slot at the bottom of the cube so they press on the sliding bars and secure them using the brake holders.
This is easiest to do if you remove the bottom plate or a side plate and the light bulb first.

Usage

Use the handle on the bottom panel to open. Close by pressing the bottom panel towards the lamp.
