3D · Lesson 6 of 11Create a Bridged Structure

Design a Bridge Structure

Create a structure with a bridge span under 20mm.

Task

  1. 1Create two pillars - Boxes standing upright (1×3×1 units each)
  2. 2Position them apart - About 1.5 units (15mm) gap
  3. 3Create a top bridge - A box spanning across (3×0.5×1 units)

Bridge Guidelines

  • Keep spans under 20mm when possible
  • Flat bottom surface for the bridge
  • Pillars must be on the build plate (Y = 0)

The bridge will print well because it's short!
