That could be done but I have problem with time in last months :(
I think I could use bigger leaf spring and connect it in middle but I think it will need new middle mount design
No wait that's more complicated :D
That can be done but leaf spring will be long so I don't think PLA will work and also there is no pivoting mechanism so I would need to think about that two.
Because of work and many other projects I'm short with time and I don't know if printer will be able to print that so I may design that but I don't know if I can test that :(
