I am needing to make a small wedge-shaped piece with an approximately 17° angle. I need this to be somewhat flexible since it will be used to support an object for which I am not exactly sure of the angle. It's between 16° and 18°. I figure that a flexible enough material should take care of any slight difference between the angles of the wedge and the object it will be supporting. This is my first design, so I don't know what the best material would be. This design will be printed by a service like Shapeways or the ones on 3d hubs and so I want to get it right the first time. I did upload my design to 3d hubs, and I chose the rubber-like material, but the prices were way too high for my budget. I will definitely have to go with in different material. Any suggestions?
