3D perspective

grabcad

From the front point of view, this pin seems to have a huge depth.. But this is a trick, this pin has a complete flat rear, making it very easy to print. No angle over 90° so printable on any machine. The "stick" inside the "D" is meant to go through the lapel's button hole. It is quite tight so the pin should not be able to move at all. This pin is meant to remind the magic of geometry. A 3D solid object design into 2D perspective to fake a 3d solid object. How paradoxical this is.. well, this is the power of creativity and 3D printing
