Giant LEGOs-Like Lightsaber Lamp (10:1 scale)

This is a L.E.G.O.-Like minifigure lightsaber lamp. It is made 10:1 scale except for the light diffuser which is made to fit within the 256mm print height.

This lamp uses the same type of led strip like Bambu Lab WS2812B RGB LED Strip Light which is 60 LEDs/M. I have wrapped so the light rod is completely covered in the led strip. With this I have used 102 cm of the led strip.

I have tested many variations of size, thickness, diameter and shapes to find one that isn’t too thick but still fades the light. The outer diffuser is made of 3 walls.

[It can be recommended to use a higher heat resistant material like PET-G for the Light Rod and Diffuser. I have not had problems with bending but have had a user comment about a bed in his form the heat of his 12V LED strip. If you have PET-G for those parts that will be recommended]

Assembly instructions:

Step 1

Pull the LED-strip through the hole in the light rod, making sure it is rotated the same way as shown in the pictures. Then wrap the LED-strip around the rod as closely as possible, while making sure the adhesive makes good contact. At the end cut the LED-strip where the cobber part is. Finnish off by wrapping a piece of clear tape around the end to help the adhesive not come off.

Step 2

Follow the video below by assembling it in the order shown.

Cross section of the assembled lamp:

For those not using my print profile I recommend printing the inner Light Rod lying down as shown in the picture below.

This will require more support and make the rod less “round”. But what this has done for me was make the rod stronger and print better. When printing it standing up I found that it wobbled somewhat because of the flexibility in my PLA and therefore made it not completely straight. If you have PET-G or a higher heat resistant material i would recommend to use it for this part and the defuser.

If you find the light not to be defused enough I can recommend adding some foam packing material to the inside to defuse it more. I have not used it but it would help if you run into that problem.

Enjoy :)
