Description

The Plasti-Craft is a fully 3D printable RC runabout inspired by classic wooden lake cruisers. The design blends scale looks with practical RC performance and straightforward assembly.

The hull is split into multiple print-friendly sections to fit standard build plates while maintaining strength and alignment. The deck features molded plank detailing for a realistic finish, and the cockpit includes scale seating, steering wheel, and windshield for display-quality appearance.

This model is designed to be approachable for builders while still allowing flexibility in electronics setup and finishing style
