Vertical Tester

Tool for testing your vertical jump height.
The sticks I used have a diameter of 2.2–2.8 mm, and there is some clearance in the model to allow smooth spinning.
The distance between the markers is 2 cm (with small placeholders in between). I added these placeholders to reduce friction and prevent the markers above from rotating unintentionally.

If you want to have more markers, simply duplicate as many as you like and stack them on top. If you want to measure more precisely, you can make them smaller. The placeholders are 5 mm thick, and the markers are 1.5 mm thick.
Additionally, you’ll need two screws to tighten the top and bottom pieces.

Have fun!
