Ring-Light For Macro-Photography

I thought about using my LED-ring as light for macro-photography. Things seemed easy, but I wondered how to mount it to the lens. Then I looked around thingiverse and the thing 2494300 came along. That´s it!
I took the idea with the TPU-tongues and started to design my own ring, that should be as easy as possible:

I use older lenses with distance-rings on my camera. Those are about 60 mm in diameter. But I could mount the LED ring even to some of my modern sony or nicon camera-lenses, which are wider - so up to 74 mm should work.

### Parts used
- Arduino-Nano (with pre-soldered pins in my case)
- 32Bit RGB LED Ring WS2812 5V ähnl. Neopixel (11/9,5 mm diameter)
- push-button (6x6 mm)
- simple powerbank
- screws (3x10, 5x)
- double sided tape
- some wire
- an USB-cable to power the arduino

To print for the ring itself:
- housing (white)
- TPU-tongues (here blue)
- a smaller ring (here black), that holds the TPU in position
- a lid/co
