Instructions to build 2 puzzles: Grip (sheet1) & Trap (sheet2). The puzzles are very similar in construction; cut the sides for the box from a blank ~276mm x ~96mm x 18.0mm; roll the sides into a box and glue using rubber bands and CA glue. Trap also requires a 48.0mm x 48.0mm x 12.0mm bottom. Mill the pins from a blank 72.0/60.0mm x 24.0mm x24.0 in two steps with a rotation between. Use 22-24mm marbles and have fun!
