I have now come into terms with what I want to do with the whole block piece situation. After some further tests, as a whole, I have concluded that it is too much for anything other than max a couple of hours.
However, there has been another problem bothering me and my parents, which a block piece could solve: since I have gotten used to all of my equipment so we'll, there is nothing (apart from spanking) that my parents can punish me with. From experience I know that long term that will not be good for me and my mental health, and as a result I have reached an agreement with my parents. Since my father knows very many contacts in the metal fabrication industry, he will have someone make a block piece compatible with my bands. Then, they can lock it on me should I require it (it will not be used at school)
This way, I can avoid it most of the time and when I cannot, it will be for a good reason
