Need a 3d box stl file created for a dog collar transmitter

Job ID: 32003629

Budget: $10 – $50 USD

I have a dog collar transmitter with the dimensions of
Length of Case: 1-7/8"
Width of Case: 1"
Depth of Case: 3/8"

And I need an STL file (so I can 3d print it) created that I can use to encase it in. It will need a back with small holes so I can attach it to the collar.

An example of the back door of the transmitter (although since this will go around the unit it will need to be bigger) - can be found here.

I also will need 20-30 small holes on the side that doesn't open so that the sound can transmit through the outer casing.
