I've struggled with correct form during the deadlift. After a little research I discovered that my 45lb weight plates are 50mm less diameter than a standard regulation plate. This lowers the bar 25mm and increases the difficulty in proper form at the start of the movement. I designed these blocks to lift the plates 25 mm, bringing the par tot he proper height. However deadlift is an exercise that puts certain body types at a mechanical disadvantage, so there is no reason not to raise it slightly more if you are taller or have shorter arms. I designed this block to be modular - it has keyholes in the bottom to allow for lower 'booster blocks' to raise it even higher.
I've included the Fusion360 file and it is completely parametric. You can change the total lift from 25 mm to anything you wish. I did not design a booster block for this system yet, but you're welcome to.
Printed in PETG and they have held up fine. I'm not dropping the weights on them or anything, and I'm not lifting any crazy amounts either.
