Four-Way Switch train track (Brio compatible)

Four-way track split for toy train tracks, with a filament-saving design. Not only do the hollow “pockets” save on filament, they also greatly strengthen the center portion, as walls are stronger than infill (so they can hold up to, say, your kid accidentally stepping on the track repeatedly…). Slowed outer wall and top layer for quality. 3 walls + cross-hatch infill gives plenty of strength.
