RingLight 170mm

prusaprinters

RingLight with diameter of 170mm for a 12mm wide WS2812B LED-strip (144LED/m, in this configuration 50cm/72LED) controlled by a Arduino Nano. Be aware that different manufacturers of LED-strips use different sizes of LEDs and width of strips, you might need to modify the profile of the ring to match yours!This version takes it’s power directly from the USB-cable of the Nano with no extra buttons or switches, but for those of you who like modding there should be room for optional extras within the base.The LED-strip is controlled by the Nano using the FastLED-library. I found a good source of ready to use examples on Mark Kriegsman's github (https://gist.github.com/kriegsman). My personal favourite being the ‘Pacifica’. All you have to do is change the LED-driver pin to where you put yours and specify the number of LEDs. But for those with some skill in programming there's a lot you can make the LEDs do…This model is adapted to fit the mini's size of bed so that the ring can be printed in one part. All is printed in PETG using a layer height of 0.25mm. I use the standard setting of 2 perimeters and 4 solid bottom and top layers. This leaves a small void inside where i use 10% infill, depending of what sort of infill you use there will be visible patterns inside the ring this way, witch i like. The ring is printed with a clear PETG (in my case addNorth) and then sanded to give it a ‘satin’ or ‘brushed’ feel.The ring and baseplate can be printed without support as they are. The claw needs to be split in the middle and the parts can then be printed without support. The base will most likely need support around the top opening if you print it standing in the ‘normal’ position.Printing time for all parts depends on the settings you choose, but my parts took about 6h to print. Modelfile included in Autodesk Fusion 360 format (sorry, a very quick and dirty version witch might be somewhat hard to find your way around). Sample video of ‘Pacifica’ animation running…
