About this 3D model

Men in blacks neuralyzer from 1997, 3d printable and prepared for electronics as well. Needed to build this is a spring, 10x3 round magnet, 3mm screw with flat head and glue. I have designed this so it's adjustable tension from magnet by tighten or loosing the 3mm flathead screw. I have schematic and pcb file for the neuralyzer in diptrace format.
