I am considering getting a 3D printer but I promised myself (and my wife) that I would first get to grips with the basics of CAD design so I don't end up with either an expensive paperweight or 3000 benchies...
I am following the Freecad tutorial that Irv made and I can follow the steps he takes and I understand them as well so far so good.
Besides the tutorial I am trying to design some things myself, one of them is a dustcover for our e-bikes to cover the contacts when not in use and the battery is removed. There is a ready to go model in Thingiverse but that defeats the purpose of me wanting to learn to design it myself.
One aspect that I am not getting on how to design is what you can see in the attached pictures, on the mounting bracket on the bike there are three 'mushroom' shaped pins and on the bottom side of the battery there are the three corresponding keyhole shaped recesses.
I can design the shape of the recess but I don't know how to create the 'overhang' that encloses the pin when you twist the battery on the mounting plate.
The ready made one on thingiverse is this one: https://www.thingiverse.com/thing:2732426
It seems so simple but I can't seem to figure it out. Can anyone give me some guidance on how to design that feature?
