Description

One of the activities of our team is the teaching and development of experiments for STEM education in Uni for kids . And one such experiment was an experiment visualizing how the hadron collider works and how the solenoid works. So, as a result, we have that:

Colider

But for the development of this experiment, we need a roll bender. Unfortunately, there is really hard to find a small one and a cheap one, so after some googling we find this and later this one

And after some designing and development, we develop own version of this tool that is robust and 3d-printable.
