PLTW Train

thingiverse

I'm building a 3D train for my PLTW class. Print each part once, except you'll need four wheels, four axle pegs, four linkage pegs, and two linkage arms. A windshield isn't required. I recommend not printing the hitch peg and hitch magnet - if you do print them, make the hitch magnet slightly larger and the hitch peg slightly smaller. If building a 75% scale model: Print axle pegs at 90% Print linkage pegs at 60% Print cow catcher at 95% Print everything else at 75%
