I am taking a CAD class at a local community college. This class is a part of a larger program for manufacturing tech. I am just doing the CAD and in the spring term the 3D class. (would have been helpful to know this shit BEFORE I started building the workshop!) The instructor is looking for projects the students in his CNC classes to make. I suggested the 1/4" spacers and he was interested. If there is enough interest from the ATV community, he could sell them through Ebay with the proceeds going to the college.
