Vertical jump test

A tool to test how high you can jump. Add the 1cm tall rungs to the pole and then put the peg into the hole where the semicircle is facing away from the rungs. Line the peg hole with the opening in the main piece and insert the small peg so that the big part is facing away from the rungs. Mount where the pegs are on top. The more rungs you can move, the higher you can jump. Measure how high the first rung is to know how high every consecutive 1 cm rung is. It took many attempts to make it this good, but the sum of all the failed versions is still cheaper than buying a real one.
