Track Cleaning Car - N Scale

thingiverse

This is a "drum style" track cleaning car - perfect for precision work. Printing lies flat on top, requiring no support or raft setup. To assemble the car, you'll need two commercial trucks and truck pins. Fill the drum with pennies (which should fit snugly) and wrap it in a strip of paper towel to keep them secure. The car's wells are designed specifically for holding pennies, and adding more will actually make it less likely to derail - although this may also make it harder to pull smoothly.
