Yes looks familiar, I also used hardware fabric, I have a new design I am working on, the square was OK but I did not like lifting it on an off as it always caught the sides of the CNC plates and eventually would scratch something up, I made a cylinder now that I just tested and it works just as good as the box I need to finish up a top on it I will post a pic when I get it finished. Already looks a ton better
i used some duct tape around the bottom, works fine, but i do want to get some nicer metal, adjust the size just a bit, but i have a good mock up to go by
you want any of the extra 7193 tubes i have now ?
