About this 3D model

I like the new EZStruder from Seemecnc, but I miss watching the gears of Steve's Extruder to see that it is working properly. I made this silly little indicator and it does the trick. The STL file has the hole dia at 5mm. Its a press fit on the motor shaft so you may need to run a drill bit into the hole or scale the STL file slightly before slicing to accomodate shrinkage of the plastic.
