offset corner clamp

I designed these corner clamps as simple as possible, however, I implemented a new idea which is an offset tension due to the channel inside the blocks. The idea is to use it with small items, with an elastic band, for quick application and removal. I have tested these blocks, with and without offset, and to me, it has worked much better than the traditional designs. I kept the model as simple as possible, so it does not make it difficult to understand the basic idea, reverse engineering and make variations with additional developments.
