About this 3D model

My Mix G1 3D printer came with smaller endstop switches than what the replacement STL files had. Therefore, I made my own switch holder. This attaches a micro switch that's 14mm long with 7mm hole spacing to a 8mm rod (I have a smooth rod but I don't see why threaded won't work). I apologize in advance for the very bad job with FreeCAD, but the part works anyway as long as you don't try to change it ;)
