Ski rack for repair

My father needed an holer for the ski to work on them, maily for sharpen the blade and put the wax on. I saw the price of this parts online an the price was sincerly to high in my opinion, so i dedice to go trought it and design my own. To add a bit ok complexity i also used some topology optimization tools.
The holder can be tilted in two position in order to work on the ski in two different position, as in the figures.

To complete the project you need 4 inserts M8, two screw M8 with a minimum length of 65 mm and two nut M8
