Spiral Plow

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.(update) after testing the plow i found that the diameter of the rod was too small, so here is two more moddels. the "rod 2" which will slide over the first rod if you have already printed it, and the "rod 2 without rod 1" which will fit on the spike if you have not yet printed the
