Kettlebell

thingiverse

This design was sparked by @natrium's version found at https://www.thingiverse.com/thing:2086852. Unfortunately, his 30mm shaft wouldn't fit my weights, so I created a new one that gives my hand more room. This design should accommodate all 1" hole weights. When using this product, be cautious not to let the nut spin off and avoid dropping it at all costs. I disclaim any responsibility for its durability. In my test, 15 pounds felt ideal on it, but I would advise against using more than 30 pounds.
