Weight lifting plates

thingiverse

I designed some printable weights for exercise purposes. They are a 2 piece shell that can be glued together and filled with concrete. Listed weight is not going to be exact, but it is based on the weight of concrete that can fit inside the hollow portion of the cavity; not filling it all the way or leaving air bubbles will reduce the weight. The weight of the shell is not factored into the overall weight. The top and bottom are 2mm thick and the walls are 4mm thick, they should hold up reasonably well so long as you don't slam them around on concrete. I will add more as I get time to do the math and design the plates. 45 lb ollympic plate measures 338mm outside diameter x 104.5mm outside height with a 2.125" center hole to allow it to fit on olympic size bars 25 lb plate is 308mm outside diameter x 72mm outside height with a 1.125" center hole to allow it to fit on most dumbbells
