Meant for light weights and the typical cheap 52mm ID plates. Pretty niche design, not sure if it's useful to others, and very much a hack.
Don't overload it and definitely be careful not to use it with anyone else running around who could be hurt if it fails! I have no idea if it works with any heavier plates!
I made it because I got some plates on black Friday to hold down equipment, and thought I might as well but the handle so I could actually work out with them too.
I made this to attach 2x 2.5lb plates to a handle. It might not fit high quality plates with smaller holes.
I have absolutely no clue what this would do with heavier plates, or if that would even be safe…. and I suspect that it would not be.
The clamps seem to loosen a lot by themselves, but that could just be the dumbell itself. Printing the end caps in 100% infill to be able to tighten them more might be a good plan.
The spacers are designed to be just a little shorter than the plates, to allow the clamp and washer that comes with the dumbell to compress the plates.
The ¾ version is untested, and I have no idea how well it fits when you start stacking multiple plates. It works well for 2x 2.5lb plates but that's about all I know!
