A multi tool holder for diffrent bikes. It is mounted on the bottle holder. So it´s only usefull if you often bike without a bottle (because you´re using a camel back for example).

So now everything you need is safley stored centered on the downtube.

For printing i recommend TPU or Carbon xt cf20
