This model is 25.4 times too small. Solidworks also tends to crash with this model.

The model is very detailed, BUT ...
size is incorrect. The model is 25.4 times smaller than the real one.

The model is rich of detail but unfortunately the dimension are not correct

the file works fine. It is just heavy and out of size. I belief that having all electronic components it is not to useful for modelling. 
I just loose...

The dimensions are wrong.

I concur that this model is hopeless. Useless piece of model.

Causes Solidworks to crash.  So does the STEP version, and so does the IGES version.  It is not to scale, and trying to scale it causes crashes too.  ...

As previously noted, the dimensions are incorrect. It seems like it was scaled incorrectly, perhaps when going from metric to inches or vice versa.

Thank you for your model.  I was getting ready to model the part but I found your model.  you saved me time and your model is spot on.
