3D · Lesson 4 of 11Create a Peg and Hole

Design Mating Parts

Let's create two parts that fit together: a peg and a hole.

Task

  1. 1Create a base with hole - A box (4×1×4 units) with a cylinder removed
  2. 2Create a peg - A cylinder (diameter ~0.9 units, height 2 units)
  3. 3The peg should be slightly smaller than the hole for tolerance!

Tolerance Applied

  • Hole diameter: 1 unit (10mm)
  • Peg diameter: ~0.97 units (9.7mm)
  • This 0.3mm gap allows them to fit together

Position both parts on the build plate!
