Hi. I made a holder that fits in my tool holder for a Dremel. I saw a lot of negative comments about this idea because it is flimsy. I built mine to be pretty solid, and it does just fine. Both front and rear brackets are lathe bored. The top strap in the rear is hammer forged without final machining. It just serves to push the back of the Dremel into it. The grinding was rough, but it finished a custom shank drill. I think that it's successful. Picture attached. Hmmm. I'm having some problems. I'll try again later.
