I've been 3D printing with a Printrbot Simple Metal since 2014. In that time I learned some CAD modeling in Onshape and have been designing many things. Recently I've needed a 3D printer that prints in better quality, has a bigger build volume, can print faster, and prints more precisely than the Printrbot. So I bought an Ultimaker Original+, and built it. And now I am printing everything I ever wanted!
