I made this extension cord cover, around $1 per foot in filament cost

The goal of this project is to design a cover for an 8mm⌀ extension cord at my makerspace, strong enough to walk on, at minimum cost. The parts assemble to form a rigid triangle, with the top in compression and the base in tension. Filament usage: 170 g/m (52 g/ft) Filament cost at $20/kg PLA: $3.40...
