With a plate, thickness of 0.3 mm, a person has the ability to collect this designer, without the use of gums, spiders and more.
Place the structure in a layer cub, and add a ball (a ball with a substrate) of 0.5 cm in diameter, and try to pass the whole path, from the beginning of "Start" to the end.
2D models of each element, and 3D models in the Solidworks program.
Manufacturing cutting for laser scratch on the edge, with error +/- 0.01 mm
Render in Solidworks too.
