Marble Machines Board Foot v1.0

v1.0 of a foot to accompany The Tinkering Studio's Make a Marble Machines Board (https://www.instructables.com/id/Make-a-Marble-Machines-board/). We wanted to create custom feet for our marble machines board, and decided to include peg holes to offer options for 1/4" dowel use, and to make them detachable for easier board storage.
We cut ours from ~1/4" hobby plywood, and attached them to insert nuts hammered into the frame.
