Ok, we have some problems. The school printers being taken, we asked someone to print the parts for us. After some problems, especially related to the axes because too small, we finally have our parts. However, the holes are too small to fit the axles. This problem can be fixed quickly and is normal in a test period, only we cannot print a new version, because the school is closed and the person who had us print the parts is not available. For the moment we are trying to file the axes to make them fit in the holes but the results are not sure.

The presentation being in 4 days, either we manage to find solutions with the axes, or we try to do something else, why not simply in cardboard and therefore facilitate the tests.
