I am looking for this model to 3D print (65161 & RL mast clamp). Perhaps @zaja.cz can chime in as this is his photo. I am excited to see your mechanical engineering innovations and look forward to learning from what you discover. I am interested in focusing on the optimization of e-foil designs using software. Have a look at the video posted towards the end of the build I previously linked. I use connectors inside the mast clamp so the motor can be removed.
Best,
Peter
