CNC Chair

CNC Furniture

In this Maker Group we’ll build a chair:

  • CAD Basics (OnShape).
  • Create the CNC Router file
  • Use a CNC Router to cut the chair
  • Assemble the chair
  • Make a cushion (optional)
*This Makergroup provides participants the autonomy to design any furniture they’d like to cut. We will not be going step-by-step through the process of designing a chair in CAD to allow for this freedom. You will design your furniture outside of the sessions. A chair file is provided if students prefer a pre-made chair instead of making their own.

Chair Materials:

  • 4’x8′ Birch Plywood sheet = $40
