This is a gear toy assembly. It is based on the filosophy of a hand toy and like a fidget spinner. The gears are helical with a helix angle of 45 degrees so that they can be mounted in a perpendicular way. All parts are included a separate STL files but you can also download the complete assembly in one single file. Please feel free to contact me if you need an further support on 3D models or if you need any customization on this model. Along with the native Solidworks file, you can also find parasolid, iges and step formats as well as stl, amf and 3mf. Polygon file is also attached.
