This is was inspired by @natrium for his version https://www.thingiverse.com/thing:2086852 Unfortunately his 30mm shaft did not fit my weights, so I decided to make my own because my hand also needed some more space. This should fit all 1" hole weights. Please use caution not to let the nut spin off during use, and do not drop (obviously). I do not take liability for product durability. For my print 15 lb felt great on it but I'd worry about using more than 30 lbs.
