In response to many requests i provide the STEP FILES so you can check or modify the 3D Model. Please give me your feedback and tell me if you need some modification or there is something missing in the model.

I am currently working on a prosthesis project that would allow children with agenesis to ski.

To ensure that the ski pole is attached to the prosthesis, I modelled a wheel clamping system.

This is the system I am presenting to you. I didn't invent anything but after searching in vain for a solution on sites offering printable 3D files, I didn't find anything adaptable according to my requirements.

This device was used for a great project of electronically assisted hand.
You can see an example at this link:
