Tried to do a more robust version which would feel safer on the finger. This one has a more geometric look which I think it's modern and minimalist.
This would be a variation of the previous option with a larger rubber band.
I tried to do an ergonomic design, which is comfortable for the finger. By adding a nice curve on the base and more holes to the rubber part, the product will be adaptable and comfortable to any hand.
On this picture, I wanted to show the curves at each end of the rubber. Thank you
