Spiral plow james
The spiral plow is very simple and does exactly what is says in the name, it is a plow which makes a spiral in the sand. it prints in three parts two which assemble to make the whole spike and the other being the plow. simply grab a piece of string tie a loop in both ends and place one on each piece, then stick the spike in the sand and drag the plow around it, you will slowly see a spiral emerge which will leave a smile anybodys face.
