This is a redesigned EdCoaster to the Edison Robot.
I wanted to redesigned the EdCoaster to better hold the programming jack in more securely, and to not have the lead caught underneath coaster every time I move it.
While I was at it, I re-aligned the hole and the port perpendicular to the top face and changed the channel underneath to hold the lead in place. (see section image)
Used ABS 1.75mm (Silver) Filament from X3D.
I use a .15 Res otherwise the top tapered surface becomes very rough
