No. We did keep trying to add a hole during the design stage - and it kept spoiling the simple lines. We never found anything that we were visually happy with. We may look at this again after its funded, and see if we can add a tiny hole that does not change the look and feel. However, if we make a tiny design change, 100% of backers would have to agree so it is fair. Otherwise, we need to keep the design the same as the photos.
December 22nd : We are working hard to find a solution to the key-chain hole. There is the possibility of designing a new hinge with a hole in the middle, but again we do not know if this is possible and we would need all of the community on board to make a design change.
In the backers section we have an update with photos and more information.
