Using an interesting array of material, RCLifeOn created a hovercraft using a 3D printer, a plastic bag, and other basic electronics, such as a brushless motor from a drone. After addressing a few challenges along the way, such as the plastic bag skirt being too thin and potentially susceptible to rips, RCLifeOn successfully created a fully-working hovercraft. The skirt could even withstand being trekked across water, sand, ice, and indoor terrain.

A recommendation for the 3D printer and list of parts is available here.
