For this sketching series I used a laser cutter in combination with a wood planer, joiner, table saw, band saw, and belt sander.

Since I knew that force sensors liked a cushion I started with some laser cutting tests with cork (which I bought at the hardware store as cork trivets and planed to the desired thickness.)
