This started as a possible package for sustainably harvested firewood. The layout produces two dollies per 4' x 8' sheet of plywood. The main feature that determines wether this can be produced is the capability of the CAD machine to rout or 'step machine' the axle. I hope you can. I have only recently completed an AutoCad course so this is student software.I enjoyed making this entry. I hope you have more contests in the future.
