About this 3D model

This is a prototype for a gel comb intended for use in gel electrophoresis. It has been modelled using a Bio-Rad gel comb for reference. I broke the design into two pieces so everything could be printed without supports (though there is a small dimple on the bottom side of the vertical comb component). The thickness of the comb teeth has been gradated to determine what the ideal dimension is. I have not printed this item yet.
