This Christmas decoration star is illuminated with an LED strip.
I designed it to have a nice advent decoration with functions also as an ambience light.
Some details about the designing process you can explore in my video. (German language)
I provide also DIY-Kits with already printed stars and the proper LED-stripe:
See the video form ScienceMadeFunner. He made a video as he printed this thing. His modification is wonderful. https://youtu.be/lkWRz-czdd0
The parts are designed to print with a extrusion width of 0.4mm. Why this is important i explain in the video. But for short, it is because of the vertical wall thickness is 0.8mm.
Some slicers like Sli3r need a extrusion width settings of 0.44mm to get perimeters with 0.4mm width.
The Stars you have to print. Then you need some 10mm wide and 74mm long LED-stripes. For isolation some shrink tubing is recommended.
You also need some wire, an 12V power adapter (500mA for 4 stars) and the tools you see.
Main design features
I like to bring up the following design features:
- The Wall thickness is optimized to give a uniform light distribution
- The two half of the star mount without any additional connecting element
- There are two ways to mount the star (#1 to a 5mm rod or #2 to a wall) in both ways the groove has his function!
- The LED stripe form-fit to his position. Because glue will not hold enough over time.
Again you can watch my YouTube Video where i explain it in German.
Bad light distribution with the wrong wall thickness.
Good light distribution when the extrusion width matches 0.5x the horizontal wall thickness.
