Not only that, but a Mod 0.5 20-tooth gear downloaded from Thingiverse printed successfully and runs as well! I wouldn’t expect the wheels to hold the track at speed through a turnout. And the spur gear is […]

Replicating Percy

By using 3D printing, I should be able to save time in my experiments with Percy. That in turn means I will be able to learn more in the same length of time. Indeed, I should be able to run so many experiments, that I can afford to change one variable at a time. The […]

Deconstructing Percy
