IntroductionI have built a B-Robot as designed by jjrobotshttps://www.thingiverse.com/thing:2306541I was happy with most of the parts (although I redesigned many pieces in OpenSCAD as I wanted to modify them) but I had problems with the wheels - it is very difficult to accurately print a D-profiled hole that will fit neatly onto a stepper motor's shaft.
