3D print the parts and warm up the hot glue gun.
First, you will need the R1 parts (they have the middle partition, orange ones). The sides with one dot have to be inside the first tube (the first row). Place them around the tube in 60 degrees steps and fix them with a hot glue gun. Next step is to glue another 6 paper tubes (the second row) around the central one.
These 6 tubes (the second row) are vertically secured with R2 parts (the green ones). These have symmetrical sides, so there is no special requirements for the position.
Next step is to place R3 parts (blue). There are always two of them in each tube (of the second row). R3 parts have on one side 2 dots. The side with the dots must be inside the tube (the second row). Then add another 6 tubes (which will be creating the third row).
Then you have to place the R4 parts (the red ones). There are always two of them in each tube (of the
third row). R4 parts have on one side 3 dots. The side with the dots must be inside the tube (of the third row). Parts are not symmetrical, they are sloping on one side. The lower part directs upwards. Finally, you are ready to add the last fourth row of 6 tubes. The body is finished.
Next step is to prepare the wire and the bulb. The choice of the switch, the light bulb socket, the light bulb, and the outlet plug is up to you in dependency on your country system. When installing the cable through the top part, remember to leave a couple of centimeters there, co the bulb socket is NOT directly under the 3D printed part. If you place it too close, the plastic part will be destroyed by the heat. Secure the wire with a screw. Do not forget to protect the cable with 3D printed cable protector. Pres the top element into the top tube. Use glue if needed.
