Just a simple ring to mount two 5mm white LEDs in for my wife to use while she's crocheting or beading so she can see the details better.

I accidentally modeled it upside down in fusion, so you'll have to flip the model in your slicer to print it.

I attached the f3d file if you want to customize it/make a larger ring. I tried to parameterize it, so if you want to change the ring size, adjust the parameter and it "should" scale properly....

I just used two 5mm white LEDs, two 1kohm resisters, and a micro-usb breakout board.
