This is my new design for a diy darts ring light.

Connected to the dart board by four little magnets in each feet. I glued the magnets in place with some glue (based on cyanacrylat). 

I used this LED strip: https://www.amazon.de/dp/B0B24M5NYC?ref=ppx_yo2ov_dt_b_product_details&th=1 : 2 m

Use the cable channel to clamp the LED cable to the side of one of the feet.

Separate the file in your slicer (right click on the model > separate > to objects) and multiply the parts using the print list.

Print List:

• 9x ring element
• 3-4 feet
• 9x connectors
• 1x cable duct

Other Parts:

• 12-16 neodymium magnets (4 piece per feet) D=10 mm, t=2 mm
• LED strip (2 m)
• glue (based on cyanacrylat)

Print Settings:

• i used PLA+
• no supports
