About this 3D model
This is a digital version of the Opto Endstop 2.1 for use in your 3d assembly models. It was designed in Autodesk Inventor 2010, I have included 4 file types IPT STL STP and IGES. With these four file types you should be able to open in many types of software. If there are any requests, for other file types I may or may not be able to help but do let me know.
