I just found out a few days ago that there is a MakerSpace offered by Ting Mobile near my house that offers the use of CAD software computers and 3D printers to the public. I am planning on making a new prototype for the buoy made of ABS plastic. the good thing about ABS is that it is water resistant, strong, and non-toxic. The bad thing about it is that it really is not recommended for extended outdoor use which worries me but i'm thinking there is probably some protective substance that could be applied onto the finished product to help give it more shelf life outdoors. I'm also looking into the price estimate to use the MakerSpace and 3D materials usage which I am thinking right now to be possibly around a good $30.
