Loading Pin
thingiverse
This loading pin can be used to increase body weight for excercise. Mine can hold more than 40kg. You need weight, a harness and rope, to attach it to your body. If your printer is to small there is also a two part version which screws together. If you find my design lacking you can use the .step design files to improve on it.
